In Korvara dungeons, remains aren't properly clearing fully when harvested from bonesaws. They are not visually there, but you can still mouse over them. They can't be harvested again, but it makes it impossible to click on tiles previously occupied by remains, making it impossible to do things like gather certain resources without the use of WASD mode, or reclaim bear traps.

I would have a screenshot of it, but I can't seem to get my mouse cursor to show up on screenshots.

Tested to not be an issue in 'normal' Sigrogana, at least in the goblin cave near Dormeho.

This also tends to happen with Chimera's eating trait.

This should be corrected in 2.60d. There is also a maximum spawn of 8 per dungeon at a time.
