The only thing I see in the Bugs forum is
https://www.project1999.com/forums/s...d.php?t=437913 (an issue with decaying skeletons being too rich).
However, it's very possible Nilbog had a previous issue to (clasically) remove those skeletons, and he decided to kill two birds in one git commit (ie. code change) when he fixed the above issue ... if they're even related (how long have the skeletons been gone?).
You could do some more extensive bug forum searching if you're curious: I only looked at the recent tickets.
