Yes, it was, although that doesn't rule out other sources of HW corruption; however I've noticed no other instabilities...

You people are awesome, thank you!

No, if you can that would be awesome! Attached is the latest autosave.

Thanks!

Just in case this is interesting, below is the initial crash that happened first, before the one loading the corrupted save (if it's a result of rendering a corrupted map then probably isn't).

Factorio crashed. Generating symbolized stacktrace ...

Right, I figured; interesting that all 3 autosaves are bad, so the game itself crashed long after writing several bad saves, any ideas on what causes it? (I doubt RAM corruption as I've got ECC RAM on one of the computers, but it's possible). Thanks for the reply, I'll post the other crash tomorrow ...

I encountered a crash today while playing, then again on loading a recent save from the same session. I can reproduce this on two different computers, both running Linux (Fedora 25).
