Nope, i've been playing on that same save (the last autosave) for a while and i haven't been able to reproduce it. Drive's SMART info shows no issues, firmware is also up to date.

Non-blocking saves are enabled, i'm not sure what actually caused this, i had factorio open in the background and came back to this when i tabbed back in.

Whenever i try to save it fails and returns a I/O error in the UI, and upon exiting the save the entire game crashed.

I've attached the log ...
