you log does not indicate versions of mod\forge\mc.
are you sure that you installed everything properly and use latest versions?
Thanks for your response
I use latest versions
FML: MCP v7.26a FML v188.8.131.526 Minecraft Forge 184.108.40.2064
and IC2 [IndustrialCraft 2] (industrialcraft-2_1.115.231-lf.jar)
I am completly clueless the only thing I can do now seems to remove IC2 completly otherwise I cant even log into the world any more since the chunk with the mine is effected.
After successfully logging in again I will try to reinstall.
