Moldy dungeon generated with 2 stair cases to surface, both cause crash when climbing them
Version 3.0.6 r88
MS dos ASCII version
running on windows 10 via Dosbox 0.74
The moldy dungeon level 1 was generated with 2 up stair cases. Going up the stair case that you enter from the surface results in a "CRITICAL INTERNAL ERROR: Signal 291 was raised" fault and using the other staircase to go up results in an "illegal hive" error. Both crash the game at that point. Going down to the lower levels isn't an issue.
I have a copy of the save game file with this issue
