More fixes this week. Mostly dungeon-hardening, including a new internal dungeon-tester utility I am running before each build. Like a unit test for testing dungeon continuity.
(For the technically curious: it uses a heatmap calculating walkable distance for every tile in the level, from the entry stairs, counting only passable or destructable tiles or openable doors to ensure each down stairs can be reached from the entry stairs.)
This week my focus is on some more generation issues, the ghost currency fix, and a few other reported issues.
