I have a broken gas pipe attached to the output of a gas reservoir. The pipe broke because the steam cooled down while inside the reservoir and became water when entering the pipe. Deconstructing the gas pipe causes the game to crash. Repairing the gas pipe first prevents the crash. I'm playing the current version (Development build SU-291640) on Steam on Windows 10. I have no mods installed. Divers Cycle 321.sav
If you disable a hydrofan and then enable it again, the dupes won't use it any more. To work around this you have to deconstruct it and construct a new one. Side note: It would be neat if we could set a target temperature for the hydrofan. I just want to keep the nearby buildings from overheating; the dupes shouldn't have to push the temperature below freezing.
