Escape shuttle decompression via building = Bad

[Spy_Guy]

It seems to be specific to building walls in certain locations in rooms. Building one in one spot: Fine. Building in one spot over: Deadly.
It's almost like walls are blocking invisible air vents. And somehow prevent oxygen from reaching certain areas. The north side of mechanics is one such spot. Western wall in the main hallway south of research entrance is another (just above the vending machines). It's bizarre.

Has this happened recently?
