Ahhh.. then I might know a fix! Go into your forge.cfg and set removing crashing entities to true ~
Hm, i can't find "removing crashing entities". Just "removeErroringEntities" and "removeErroringTileEntities".
What do you mean?
If i set both to true it crashed again.

Oh, should i upgrade EnderIO, AE2 and ThaumicEnergistics and set the removingErroringEntities/Tile Entities to true?
It is sooooo complicated...
