doing some research, i found that the FTB Ultimate Reloaded modpack for minecraft 1.12.2 contains "chunky turtles"! it uses a mod called "PeripheralsPlusOne". would loveee to have this mod :)

Thanks! I'll look into it although the mod seems to no longer be available for download in CurseForge, and was not updated in 4 years, so it's not looking good. You can experiment adding it yourself manually (from and report back!

I just downloaded the tekkit 2 server thing. i have done vanilla servers in the past. When i run the LaunchServer.bat it says "[Tekkit 2] Server is starting... A problem occurred running the Server at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke( at java.base/java.lang.reflect.Method.invoke( at at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main( Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class (jdk.internal.loader.ClassLoaders$AppClassLoader and are in module java.base of loader 'bootstrap') at net.minecraft.launchwrapper.Launch.<init>( at net.minecraft.launchwrapper.Launch.main( at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke( ... 3 more Press any key to continue . . ." Any ideas on what is going on? Please let me know. Thank you

Hey! You need to make sure you only have Java SE 8 64 bit installed on your computer (alternatively you'd need to manually edit the path).

If you already have Java 8 and get that error, you need a newer Java 8 version

I have a turtle that can self replicate, but it needs to travel very far sometimes for the diamonds and trees. i need a chunkloader that can follow it. using worldspikes would simply be too many active chunks needed. there are more then one mods capable of doing this but here's a great one: would like the mod named "Misc Peripherals". one of its items is The Chunk Loader Module. Craft a Chunk Loader Module (shown above) alongside a turtle to make a Chunk Loader turtle. The module can be crafted with any of the following chunk loaders: Railcraft World Anchor ChichenChunks Chunk Loader ChickenChunks Spot Loader Additional Pipes Teleport Tether Steve's Carts Chunk Loader Module

Misc Peripherals is not available for Minecraft 1.12.2 unfortunately. I'll stay on the look for an addon mod with a similar ability, but feel free to recommend other ones as well!

Could you also add Ae2 and extra cells along with it too?

Hello, could you add Extra planets to this modpack? I would love to explore more planets.

To be more specific, I have an MFSU using Glass fibre cable to connect to a Galacticraft Energy Storage Cluster. from the cluster, galacticraft heavy aluminum wire goes from the cluster to the Galacticcraft "Refinery". using an EU-Reader it only consumes 4.7 EU/t, adding more refineries (so long as the battery has power) doesn't change this, they all use only 4.7 EU/t each. just seems low for power use, its too easy to power 64 of them at once :) Note: If i could suggest one thing to add, it would be a mod that allows Turtles to keep the chunk they are in loaded. there are several mods like this that add things like the "Chunk loader module" that can be added to turtles. I have several turtles things i would like to try but if the chunk unloads it messes it up.

Thank you for the feedback! I will look into it. Regarding turtle chunk loading, you can try using Worldspikes or suggest any other mod :)

Hello Hello, me and my friends Really like this modpack, but in our opinnion there are some important mods missing.. Like mystcraft, Thermal series and Appplied Energistics! But all in one its a good modpack but a bit diffrent to the original Tekkit we know ^^
Spetzi123 1 year ago
Hey, thank you for the feedback! Indeed Tekkit 2 is a continuation of Tekkit Classic rather than what is now known as Tekkit. Thank you for the feedback nevertheless, and perhaps consider checking out my other modpack (The 1.12.2 Pack) :)
Posted by xJon 1 year ago | Modpack Creator
serveral galacticcraft items liek the refinery say things like "power required: 93 EU/t" and this is very wrong. it uses 4.7eu only!. i setup a nuclear reactor to power a couple of them and it turned out i could easily power 64 of them at once... they uses too little energy in my opinion, all the descriptions say a number much larger then what I've observed

Hey! If you can report the specific details (e.g. exact machine) I'd love to thoroughly test this :)

As someone who previously only played tekkit classic, this mod pack has been AMAZING. so much fun with my friends again, nostalgic for us all. thankful for this modpack! here are some "issues" I've run into. some blocks seem to have little information online, Can't find much info about how to use the steam generators, and water mill arrays don't mention how big of a area of water they actually need, its quite large. the large water mill array seems a little weak too, i understand its more powerful when water is placed directly inside but there is seemingly no way to automate that. the advanced information display doesn't seem to work with the information panel extenders like the normal one can. when using an Artoretum with orange trees, it does NOT pickup the oranges, making the jaffa cake factory a bit difficult, had to use void rings on pedestals... it works just fine with jungle trees with cocoa beans tho. its possible its a setting but the alarms are limited to a max of 64 blocks, when i preferred having the ability to raise that to 128 in tekkit classic :) (im not in love with the wakeup message, for anyone else looking to change it, you can change it in the morpheus.cfg file in the config folder) besides the several machines i cant seem to find information about online, in LOVE with this modpack

Hey, thank you for the feedback and I'm glad you've been enjoying the pack :) First of all, regarding mod information I recommend you to check out or the pinned message in the #tekkit-2 channel of Technic's Discord. They both have updated links to mods' wikis. In regards to the displays, I'm pretty sure there are multiple types and you need to match an advanced display type with an advanced extender. In regards to Forestry's support of orange trees, this is a known bug that we hope to resolve. I will also look into the max range of alarms, and let me know if you have a suggestion for a different wakeup message!

Hi, I would like to know if you have any item to load chunks. I saw one from railcraft but I don't know how to make it work, could you help me please. (Personal Worldspike and World Anchor)

You can hover over the slot in the Worldspikes in order to see the fuel requirements :)

Hi, i was really happy about this modpack coming out. But I have some issues. There is multiple items missing, the most notable is oxygen pipe. Its just not in the Galacticraft mode. Can you add it please? Or is that just some bug?
Dr_Virus12 1 year ago
It should be there! You can feel free to ask for more support in Technic's Discord :)

Since I cant find anyone asking this question, how do we give banners patterns? JEI gives me a recipe but I have no idea what to use to create a banner with a pattern.

Mě žádný ze serveru Tekkit Clasic ani Tekkit 2 nefunguji správně. U Tekkit Classic můžu jen Já se připojit na můj sever, ale kámoš se nemůže připojit a server Tekkit 2 nefunguje - spustí se, ale nejde se na něj připojit. Prosím o pomoc.

Můžete požádat o pomoc v angličtině přes Technic's Discord, jak nastavit server
Posted by xJon 1 year ago | Modpack Creator
Já vím jak nastavit server. Mám ho nastavený správně. Nastavil jsem si ho a fungoval mi, ale další den už nefungoval. Díky.

Is this mod pack compatible with an Intel based MacBook? Really want to relive some nostalgia but don't have a windows computer. Thanks for your help!

Good evening, was it possible to update the logistics pipes to the latest version? (I don't know if it's the latest version). Have you thought about the extra planets addon for galacticcraft?
kolektivista 1 year ago
It will be updated to the latest version in the next modpack update (should come out next month). And thank you for the suggestion :)
Posted by xJon 1 year ago | Modpack Creator
Can a mod like waila/hwyla be included? It would be helpful to see what mod each item is by pointing at it.

Hello. First time replying in a blog. Wanted to ask if it was possible to earn xp for shift clicking items into your inventory? When I macerate or smelt, etc something, I get xp when I simply left click to grab the item, but when I shift click to send it to my inventory, I get no xp. Just wondering if this was something that could be fixed. Thanks. Have a great day! :)

Thank you for the bug report! I've forwarded it to the author of IC2 Classic so hopefully it will be resolved in the next update :)

Hey is it possible to patch potions of instant damage and bee hives going straight through the best armors in the game?
ChiseledChin 1 year ago
I'll look into that - thank you for the feedback!
Posted by xJon 1 year ago | Modpack Creator
Magic damage (from potions) is supposed to bypass armor, but we'll change the bees to respect armor in the next update.

Is there any possibility that, Simple Storage Network or Refined Storage will be added? Since Logistics pipes is in beta testing on 1.12.2 version. Missing Tesla Core Lib for Industrial Foregoing speed & energy upgrades.
Jajsemdobrej 1 year ago
And I wanna ask if it´s possible to add Compact Machines to modpack to save space in the house
Posted by Jajsemdobrej 1 year ago
It doesn't work or am I doing it wrong? Logistics EU Power Provider has stored energy. There is Basic Logistics Pipe next to it with Power Transportation Upgrade. A few Unrouted Transportation Pipe, Basic Logistics Pipe with EU LV Power Supplier Upgrade and Macerator next to it. Everything is in a straight line. The macerator receives no energy.
Plastian 1 year ago
I am pretty sure the Power Providers are unimplemented in 1.12.2 unfortunately. You can ask about it over their Discord:

But transporting RF works very well
