Issue happens in the map arid-dng/second/f0/entrance, or any map that uses the -1 heightmap tiles adjacent to a high-number heightmap tile that is greater than the map's elevation levels. This map has elevations 0, 1, and 2. So the heightmap tiles specifying 4 are used to create interior walls.
On the south border of 4 and -1, black tiles will appear in the pit when you generate heights.
Before generating heights:
After generating heights:
These black tiles are drawn in the Below (0) layer of the map. This always happens in heightmaps with interior walls bordering pits on the south. This is a minor annoyance more than anything since they need to be manually erased after generating heights.
