Rapid phase change of CO2 causes creation of gas from nothing

Hello,

I have noticed my base suddenly being flooded by CO2.

Upon investigation i found out that there vere massive amounts of CO2 pooled in one of my cold biomes where i have a pseudofarm for Sleet Wheat. After some time i have noticed the point where it is comming from.

I also happen to have 2 AETN machines in this giant cold biome so it is hooked up and was used foor cooling.
Since i didnt need it for a time i just made it loop to store cold, then i realised that it is comming straight through my "farm", so i have turned 3 segments of the insulated pipe into radiant one.

And that is the spot where i noticed weird stuff going on. The biome had some small amount of CO2 from everyday stuff (no more than about 500g per tile).
When this CO2 came in to contact with the extremely cold radiant pipe (it was aproaching the lowest point the AETN can get) the CO2 instantly phase changes to liquid and to solid right after that. When this solid touches down to the farm tile below it it rapidly warms up and phase changes back to liquid and gas.

The funky thing is that for some reason the amount of CO2 phase changing back to gas is much higher than what originaly condensed.

I have tried to fill the entire biome witch just 1kg of CO2 (using debug) and its instantly observable that the CO2 pressure starts to rise rapidly aroud the 3 radiant pipe segments.

First time i noticed thie higher levels of CO2 in my base i spotted quite a lot of tiles filled with 2000kg of liquid CO2 and my base was starting to get completely overwhelmed by the gas.

 

Looks like a bug in the simulation if the element rapidly changes its states.

I am attaching a save file as it is best seen in action (dont judge my base :mad:).

Steps to Reproduce
Load my save file and observer the sleet wheat farm.

@Hellium What a coincidence, I just posted a similar bug which is likely due to the phase change of water/steam. But are you only seeing the issue with CO2? No other gasses being multiplied?

So far i have only noticed it with CO2, but i only have this kind of big temperature difference in this one spot.
