Abyss pits from spires failing to close properly.

Hello!

When killing abyss spires occasionally one of their pits will fail to close. The mini-map icon will indicate a pit and the pit will continuously spawn a trickle of monsters as far as I can tell infinitely. This happens to both mini spires generated by the the Abyss Scarab of the Edifice and the normal spires generated at the end of abysses. The exact reason why that happens I could not pinpoint. Can be quite annoying when running the Edifice scarab since you can't tell the "fake" unclosed abysses from the fresh ones on the mini-map.

can't take a screenshot. For some reason all I'm getting is a black screen.
