I beat the crypt with Changeling. My maximum gold should have risen from 160 to 165 but it didn't. I can't think of any sensible explanation for this, so it seems like a bug to me. I'm not sure if the other challenge dungeons have similar bugs, e.g. not giving rewards.

The changeling was added after everything else. This is the problem with the GM build that you all know as the freeware, it's really difficult changing anything. That's why the full is designed differently, to allow for expansion, etc.
