my entire game went kablooey
i use a large amount of mods so it may be a mod conflict but i figured i would start here and figure out where to go next

Your error report is pointing to foam fix. From a quick run over of the log, I see nothing about Chance cubes in it.

From what I can see, it could be one of the CC rewards tried to modify the blockstates on realworld's Mango fruit block causing the crash.

wow that was a fast reply :D i'll take out foamfix and see if that fixes anything!!

Foamfix is the mod that is directly trying to change the block state. I don't deny Chance Cubes may have something to do with triggering the error, but there's nothing to give me any indication that chance cubes did anything

i decided to take out realworld and so far the game hasn't crashed on me. however i will certainly take it up to the foamfix dev(s) if it happens again, since i know now that it can be a trigger for my game to crash
