I have been trying to play the Ultimate pack for a while now, but some bugs are just driving me crazy.
Whenever I try to make a new Mystcraft age, I put in Single Biomes, Plains Biome, and No weather into the book. When the world spawns, it will always become a floating island in the middle of the void. Plus, it is almost never a plains biome.
Another weird bug is whenever I try to make an iron tank anymore, it does not work. I put it together perfectly and it just doesn't work. This started happening lately because I just made an iron tank for creosote.
Finally, some little bugs like there are sometimes glitches with mobs where they will have completely white back of heads and some other spots.
If you can, just tell me what I need to do to fix these problems. If you don't know, it is fine, just wanted to know if I could fix it.
