[16.51] Crash when using alt-f4 at specific part of saving

[Maric]

I saved my game, did a little more (just one more thing ) then saved again, and so that i wouldn't be tempted to continue, I used Alt-F4 (windows). Saving did not finish, everything stood still for a few seconds and then the crash happened. I don't know what the expected behaviour should be. Abort the save? save and then quit?

Couldn't reproduce on a second try ... and its 6 am, so if someone else could try to reproduce that would be nice.

factorio-current.log is attached

btw this is my first crash in over 500 hours and nearly 5 years of factorio ... and i guess having only about 500 hours makes me sort of new at this game

Thanks for the report however I don't consider this worth working on.

This is similar to things saying "Please don't turn off the power while saving" - don't alt + F4 while saving
