Factorio Forums

What did you do?

I saved the game, attached the save file to a bug report thread in Firefox, and then attempted to overwrite the save to create a test save that better demonstrated the bug in the original thread.

What happened?

I got an in-game error dialog on the initial save attempt:
after which the game continued to work normally. However, upon clicking Save Game the second time, Factorio crashed with a Windows modal error dialog:
The same also happens shortly after clicking Quit Game, and upon attempting to start Factorio after loading finishes, whenever Firefox is still locking the save file.

What did you expect to happen?

I expected the save menu to appear, and to be able to save the game to another location.

I can't seem to reproduce the issue.
GetFileAttributesExW seems to have failed for you, but I can't reach that state no matter how I lock the file.

I have a theoretical fix but i'm reluctant of pushing it until I better understand what's happening.

Confirmed on my machine as well. File locks cause an in-game error, but no crash. I'd assumed Firefox was locking the file itself, but it must be doing something different.

Should be fixed in Version: 1.1.6.

Even though I never got to reproduce the issue, the game will no longer crash when failing to read the file attributes.
