We killed the 4th boss, Arachna, and it just didn't accept it's defeat and kept screaming.
We did get some (veggie) loot and also those little spiders after the kill, and we could continue to the next map, but it's still a bug.
Nobody got a tooth, I think.
I sounded a bit negative because I thought we missed an AP, but there isn't any, so it's OK.
This was after the patch to remove poison pools, if it matters.
