Crash when building gas bridge

And where's the save file and log file? The only way this report is useful by itself is if building any gas bridge in any situation would crash the game for everyone.

It's probably a coincidence that it crashed for you when building a gas bridge.

I've also had one crash to desktop yesterday and I did change pipes at that time, both liquid and gas.
The game was running for several (many?) hours although mostly paused.
At the time of the crash I was too tired to make a bug report...

I have a detailed report on this problem. It's definitely a gas bridge that crashes it. It's repeatable. I have another thread on this.
