Was chilling and letting the factory cook. Had a crash and it suggested I post here.
Save and logs attached. Only mods in use are Factorio Library and Rate Calculator. Crash didn't happen while I was playing, so rate calculator shouldn't be a factor.

Do you know of any way to reproduce this crash?

I do not, it didn't occur upon reloading and I have no idea what could have caused it in order to attempt to.

The only ideas I have that could cause this would be failing or failed hardware. Either bad RAM or bad CPU. Given that specific bit of logic runs for anyone using heat pipes and does not experience issues on other players computers.
