What do you mean FTB can't close the world?
What AE Crashes? What bugs with EnderIO conduits?
I'm getting the feeling there might be something up with your computer that's then effecting the game.
OS? Java version? RAM allocated to the game? Anti virus running?
FTB create the world but when i try to load it close the world, and come back to server screen...
the AE crash random.. auto craft... crafting the crates...
!!!!!!!!!!!!CAIGAN I FIND OUT THE PROBLEM!!!!!!!!!!!
Optfine... it's the problem =/ for some reason it reset the reputation of better quest.. i take it off.. and it's working again even with my old world... i'm happy.. but my FPS... is really sad... ^^''
