The original map is Lunabase. You can go below and check the box to enable rollovers, but I wanted to avoid spoilers if possible. Currently all maps are OK except Moon level 2. I'm not sure what's up with it, but the problem seems to be related to the fact that it doesn't have the standard walls around the edges.
