So today I discovered an airlock was still pumping air into a room that was WAY over pressurized. Like 1106 KG or Oxygen. I was able to reproduce the bug With a normal air vent. if there's a small biut of water on the floor over the air vent, the vent won't realize the room is overpressurized. Can possible be exploited as it is easy to reproduce. In the image provided you can see the high pressure vent(Not Underwater) Is over pressure, but the Normal vent(Underwater) Is still allowing air into the room (Which is at over 1000KG of oxygen)
Steps to Reproduce
1Place vent on floor. 2 Build pipes leading to source of air(Ie gas pump) 3 spill a little water on the vent, enough to cover like in the image. 4 Proceed to pumping air into the room, as much as you wish.
This issue has not been confirmed by a developer yet.
