No fix in sight for the non random race choices in Challenge mode. R67 generated Challenge mode gray elf chaos knight started with many stats at 99, and gets 20 skill choices per level up. Obviously broken beyond belief.

In R67 the framerate while playing in Noteye tiles mode is much worse than in the official release. It is frankly painful to play this way.
