Eureka - may have discovered the walkable area error.
1. I run the game in debug.
2. I edit one of the rooms, widening a walkable area.
3. save, but of course it doesn't save while game is running.
4. I close game, save everything, close the room, start running game in debug again.
5. The walkable area is now 100% all the way through, despite being 100% at bottom, 15% at top.
The problem could be with saving of the game while running.
Here is my room code with the wrecked walkable area. Let me know if you need anything else.
