I've noticed that when I use SkyVillages it crashes the game when loading a world. I went onto these forums looking for an answer to keep it from crashing. A short look later I found that everybody linked to the keyword "SkyVillages" had their game crashing on them too. So get rid of SkyVillages if your game is crashing. hopefully the developer will fix this somehow, or we can find a workaround, but until then, you know what to do.
