So i have this modpack whit quiet some mods, but somehow the client crashs when leaving nether. Entring the nether goes without problem, but somehow it crashs when leaving.
Complete log: https://shrib.com/#7GV7gNLvFz8I8r4Vvl9R
NOTE!!!: the error which is filling the log: "Detected an attempt by a mod null to perform game activity during mod construction. This is a serious programming error." comes from the mod "Minecraft Loader", which creates a better loading screen, but this sud not effect ingame. so i dont know, which is causing this "ticking world".
I appreciate any help i can get, even if mc 1.6.4 is so outdated.
