Do alien containment chambers have to be placed above a certain depth?

I've had no problem building alien containment chambers up to 4 stacks high in shallows or grassy biomes, but now I'm trying to build one in my new base in the Koosh Zone. However whenever i try to place it in any of the multipurpose rooms, I'm just getting the red outline of the alien containment. It even snaps into place in the center of the room but still stays red and remains unbuildable. The only difference that I can see is that the Koosh zone is at 236 meters, so I'm curious if there's a maximum depth where they can be placed, or if this is simply a bug that I should be reporting.

Never mind, found the solution. Apparently the multipurpose rooms weren't counting as being fully built, it would let me inside them and build on top of them as well as place ladders etc. But it would still let me deconstruct them with everything inside. Just had to partially deconstruct the room then rebuild it.
