CO2 geyser emitting chlorine

I believe the chlorine gas is being cooled by the liquid carbon dioxide and turning into liquid chlorine. When I remove all the gases there it only emits liquid carbon dioxide. 

I am able to reproduce the issue.

 

Steps to reproduce:

1 - Load attached save, which contains a capped CO2 geyser.

2 - Wait 30 sec (in-game) for CO2 geyser to erupt.

 

Expected behavior: CO2 geyser emits CO2.

Observed behavior: from ~90 sec, CO2 geyser begins emitting liquid Cl. After a few minutes the room contains several kg of Cl that was not present beforehand.

 

First post, hitting upload caps. I'll see if I can reply in a sec with screenshots.

30 sec.sav

Screenshot before eruption. Room contains 50g Cl from previous eruption. Room is sealed, door locked, pumps disabled.

Save attached after eruption. Room contains several kg Cl (hover text).

30 sec after.sav

Screenshot corresponding to save after eruption. Cropped to stay below upload limits. Room contains several kg Cl.

Changed Status to Known Issue

Thanks for the save.

Changed Status to Fixed

It turns out this was a long standing bug with temperature transfer. This will be fixed in the next update to the public testing branch. Your save was really helpful in reproducing the issue.
