Similar error to #499 butI don't know the reason behind it

Edit:
Don't know if it's correlated in some way but the same error happens with Biomes o'plenty (TAN being deactivated)

Also this error seems to corrupt the world while the mods are still present, as trying to open the inventory tab will crash the game.
