Not my PR!

The issue is that if you die by having a cursed ball and chain fall onto your head while descending a staircase, the screen doesn't transition to the lower level so it's not clear on which level the bones file would be generated. (Per emails from the dev team, it does get correctly generated on the lower level.) Apparently fixing this issue somehow required rewriting huge portions of the graphics engine, which probably explains the snarky comment next to the bug in the issue tracker. :-)

:) To be fair, if I was writing any program and someone came to me with a bug like that, my first thought would be "#!@? I don't want to deal with this."

Confused - the change log includes "don't show the old level when you die going down the stairs because of an iron ball"

That's one hell of a bug to find. That's kind of hilarious. That does suck about how difficult to fix though.
