Noteye goes crazy in wilderness
I exited the Caverns of Chaos, and immediately got the message "It seems to get crowded here... you discover a new settlement!" But the wilderness displayed using noteye tiles of ASCII characters. Then I started moving around, and things got even wierder, the game started displaying both normal tiles and noteye ascii at the same time.
Screenshot and save game attached.
Restoring the game from a save seems to resolve the issue, but the paladins and bishop in the new settlement still don't have tiles.
