Rename into save clones character
accidental save scumming
Problem: As long as your character has an active .bak file, if you rename your character and then immediately save (presumably, if you save before the next .bak is generated), when you go to restore, two characters will be available - the save you just made, and your most recent backup.
Solution: Rename .bak file when character is renamed.
(I feel a little guilty about this one, because I renamed a character to denote that she was surrounded by cats, saved because I wanted to delay killing one as long as possible, came back to the game next day, noticed that I'd accidentally created an opportunity to avoid the situation...and TOTALLY TOOK IT. I'm justifying it to myself by saying I earned it by discovering a bug, so hopefully this one isn't known.)
[I also got the same thrundarr target in both versions of the character - a troll. Possible that this is determined before Dwarftown is generated?]
