I added Matmos for 1.8, not 1.7.10, so it didn't work. Don't know if the Health thing worked, but it should. When you get to LVL 5 of XP, you should get 4 hearts instead of 3. If it doesn't, then please tell me.
Been working for some time to fix the Crafting Book, and I finally did it! I also added some really good resource packs if you would like to turn them on. Finally, I added MATMOS- It's also a resource pack. Have fun in Update 5!
Yogbox 2.0 is going to get some more updates the next few months. Do not use any updated that are #.#.#, as those are test builds. Bug testers can use those builds, so help out of possible please! (All updates that are #.# are okay to use.)
