Awesome! I did manage to get some weird results, where a door was placed exactly at the crosspoint of three walls. In this example there's also a door in a pool of water. But hey, that might be a trap:)
Yeah, I know this bug 😕 Messed up random bounds somewhere. But well, this was a 30 min build, so yeah ;) Can be also solved by going over the map once again and looking for a door with 3 walls near.
