Can place buildings inside other buildings

[Celarious]

On an ocean platform, on the water surface of a gas giant, it seems I'm sometimes able to place large buildings on top of other buildings, and other times I get the usual "Blocked by development at location" message:


It works too, and the building can be built afterwards:

Same with biodomes and all platforms.
So long as the origin is not inside another development's site, you can place it.

And placing buildings from orbit.

Should probably change it so that it is only platforms that can be placed from orbit.
