Created a simple interrupt for refueling on vulcanus, the interrupt condition was set to 'rocket fuel < 10' in any locomotive and the departing condition was set to full fuel in all locomotives, upon trying to run the interrupt manually, the game crashes and this is reproducible every time.

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 ...
