@yalt , I just found another issue, this one is with both the blue and red storage rooms' doors, a relatively minor issue. While you pass through them as a spectator (we have a spectator noclip through doors feature even while noclip is off, as a replacement to that annoying spectator teleporting through doors thing), you can see the void. This interferes with the smoothness of passing through the doors. The doors in the "Kabuff" area underground don't have this problem. I plan implementing an alien later where one of it properties is the ability to noclip through doors (like the specs now). As a side note, I have noticed the same issue with many of the doors on Niveus.
