Does this happen on a fresh empty IC2+GT6 world too?
Also just so you know, the Game would definitely be Ubuntu Compatible for sure (I am trying to switch everything I have to Kubuntu already, except the Windows-Only Games), and that usually means Linux and Mac Compatible aswell. But I also want it to be Windows Compatible, so I need to do that some way. OpenJDK might be the way I go unless something better than that appears. (I will definitely not require Oracle JRE to be used, like Mojang/Forge does. But OpenJDK is Oracle Java compatible, so it should work)
It happens only in My world, the world I was using while the blackout almost killed my pc. My guess is that the save is just corrupted... The save or the chunk, or both. In both cases i'm f***ed, because the chunk where I was is my main chunk. I have my whole base in it.
