I'm having trouble upgrading my map room. It wouldn't let me upgrade it. I thought it might have been because it was on the edge and there was a plant nearby but I moved the map room so it was isolated with cells all around it, and I do have the resources, but it still won't let me build it. It just beeps at me. I added an image to show the cells are empty and what it looks like when I try to upgrade.

The red areas require more of the same type of room when upgrading
