So I have this contaminated oxygen cooling loop setup and it has 10 kg blocks/cells whatever you call it of gas in the pipes. As soon as I build a insulated gas pipe to release the gas into the chamber below for collection to a battery heating system the game crashes.
Luckily my save is like 10 seconds away from the crash (at max speed). So far it crashes 100% of the time immediately after the pipe is built and a drop falls to the ground. I'm not sure which files you'll need so I just attached the .sav file.
Load the save file and run it until the insulated pipe is built and a drop of liquid falls to the ground
