The pool was empty, I tried to break it with an S Rank terra shatterer

Forge is letting TE's persist one tick after their block have been broken and idk why .-.

i was looking, and most of the last reports seems to be related to this, and in some cases its note related to breaking the mana pool or the spreader. '-'

Yep I didn't try breaking the spreader first, but its happened 3 times trying to break specific pools.
