TPPI Comes to Technic cannibalvox cannibalvox / Posted 28 days ago


Many of you have been asking for a more balance-centric mod pack. Too many of you, really. Well guess what -  You’re getting your wish.

We’re very proud to announce that Test Pack Please Ignore (“the Reddit pack”) is now live in the Technic Launcher as an official Technic pack! With a massive mod list and a custom utility mod that tweaks just about everything in the pack, TPPI is a unique play experience that will bring you your precious balance far better than Tekkit can.

We’ve been working tirelessly with the TPPI team for weeks to make this launch happen. They’re some of the hardest-working pack developers out there, so stop by /r/testpackpleaseignore and thank them for allowing us to host this, the delicious fruits of their programming labor.

ConcurrentModificationException in Java 1.8.0_20 cannibalvox cannibalvox / Posted 70 days ago

This is a warning that a few days ago, a Java update versioned 1.8.0_20 was released, which currently makes it impossible to play modded Minecraft.  The release fixed a Java bug which was hiding a bug in Forge Modloader- users with this new version of java will now receive a ConcurrentModificationException when trying to load modpacks in Minecraft 1.6+.

Forge is currently working to correct this issue, but in the meantime, we advise that you do not update your Java version to 1.8.0_20.  We instead recommend that you use one of the following versions:

Java 1.7.0_67- we highly recommend that you downgrade to this version, because it is security complete:

Java 1.8.0_11- if you need to stay on java 1.8, this is the latest version without the listed issue.  Again, there may be security updates in 1.8.0_20 not present in this version, so please use with care:

Voltz is reverting to 2.0.4 for recommended build Skuli Skuli / Posted 85 days ago

The Voltz 3.1.1 recommended build release brought to light several issues. After consulting with the Calclavia/Voltz dev team and performing extensive troubleshooting, it's been determined that no fixes will be available for any of these issues for an extended time period.
Considering this, and the Calclavia/Voltz dev team's acknowledgement that griefing will be a serious problem (even with Worldguard protections), we have no choice but to revert to 2.0.4 as the recommended build.
Build 3.1.1 will CONTINUE to be available as a development/beta build in the launcher, and will be re-promoted to recommended as soon as fixes are available.
Sorry for the inconvenience! 


Important Voltz 3.1.1 update information. Please read! Skuli Skuli / Posted 85 days ago

Voltz 3.1.1 has a bug involving grief protection on SMP servers.  The impact on single-player experience should be minimal.

We are maintaining 3.1.1 as the recommended build for the time being, until it's clear whether a timely fix will become available; if not, we'll be rolling the recommended build back to 2.0.4.  

In the meantime you can manually select 2.0.4 by selecting the small gear under the Voltz modpack icon, choose "Manually select a build", and pick 2.0.4 from the drop down menu as illustrated below:

Voltz 3.1.1 is being promoted to RECOMMENDED build today! Skuli Skuli / Posted 86 days ago

The newest update for Voltz, 3.1.1, will be promoted to RECOMMENDED shortly.
Sadly, this is almost certainly going to necessitate a COMPLETE WIPE of your existing Voltz worlds!  TAKE BACKUPS BEFORE YOU UPGRADE!
Calclavia has provided a new list of mods to include in this Voltz release.  Please note that Mekanism has been removed from the pack.  However, many mods have been added and updated:  Buildcraft, Extra Utilities, Forestry, Galacticraft, Mad Science, OpenComponents, Open Computers, Project Red, Railcraft, and Thermal Expansion (among others.)  Also, the existing Calclavia mods have seen many exciting changes!
Please note there is a hard Java 7 requirement on this pack.  If you get an error NoClassDefFoundError: java/lang/ReflectiveOperationException then you're not running Java 7.
See this Technic post for information on how to upgrade to Java 7.
The server is available here.
For a complete list of mods, view the announcement in the Voltz forum here.
There is NO UPGRADE PATH from previous versions!  Don't expect to import your existing worlds, MAKE BACKUPS BEFORE YOU DEPLOY THIS NEW VERSION.
