Not sure if intended or a bug, but after beating the murderfur, my Kerfur has gone off under possession and spawned another one. Running 0.8.2.

Guess I'm loading up on more molotovs lol. One thing that did bug out was the location; it spawned in one of the cliffs where Kerfur couldn't reach, so it just wheeled madly back and forth against the foot of the cliff and no amount of putting it on top helped. I ended up dragging it back to base and shoving it in a locker.
