bug Overpressured Vent Gas Deletion

[Beowulfe]

I'll be posting this in bugs as well, but since I don't think I've seen this posted (at least I wasn't aware of it until I ran face-first into a serious case of it), thought I'd post it here for visibility.

Overpressured vents are currently deleting gas when there's any sort of gas "fighting" for space over them. If you have, say, a room full of 2kg of Hydrogen (at max pressure for a vent), with a vent coming in and outputting Hydrogen, and two other tiles of Oxygen and CO2 fighting for space over the vent (causing the vent to temporarily no longer be over-pressured), the vent will output Hydrogen and delete the gasses fighting on top of it. This may also be connected to the gas conversion/deletion with Elecrolyzers.

To be clearer, here's some pictures showing exactly what happens, and how serious it is (this happens very rapidly and very easily):

Spoiler

Start with a room full of 2kg of Hydrogen (with hydrogen coming in and the vent at max pressure):

 

Brush in 2kg of Oxygen and 2kg of CO2 above the vent (can be any amount of gas, but to demonstrate the point...):

 

Let it run and the gasses will start fighting at the bottom, causing the vent to have room to output again:

 

After a very, surprisingly, short period of time, both the Oxygen and CO2 are... poof, completely gone and deleted, replaced by Hydrogen:

 

If this was already known and I just missed it somewhere, let me know and I'll delete the post. That being said, this seems like a pretty serious issue that could result in a lot of gas just disappearing (esp. near oxygen output vents). Realistically, oxygen output vents deleting other gasses would probably work in the player's favour, but still a relatively serious bug.

I read that you can convert O2 into H.

Yeah, I'd seen that before, though that relies on pushing spaces towards vacuum - this occurs even with tiles at 2kg+ levels, and just with an overpressured vent (which is very common in most regular ONI bases), not even with a particularly deliberate setup... which is more cause for concern for the regular player, rather than useful knowledge for those trying to maximize Elecrolyzer output.
