ToME: the Tales of Maj'Eyal

I am hoping to get a bit more information on this, but want to go ahead and post it. My Bree-man no-shop challenger has crashed ToME a total of three times now, all when resting. The mana_regen is definitely consistent in each crash, but I cannot remember if the talent cooldown finishing is. The character is a Anorithil, so mana_regen is a bit odd. The crash itself is a color-wheel of doom (non-responsive process). No clue how many red-herring there are in this bug report, and any suggestions on narrowing down the bug will be appreciated.

Weiird indeed, maybe the remote debugger can help ?
Or maybe put a util.show_backtrace() in the Actor:removeTemporaryValue to see where it comes from ?

Something like that happened to me too. The game froze on Tol Falas and there was a message about mana regen. As I didnt save my char before going there, he was lost after I killed t-engine.

I haven't seen the crash again, but I think it may be related to one of the wights casting Thunderstorm. Not confirmed, though...
