After saving Illustrator file it looks unsaved

[#1]

Hi! I have this really annoying thing that after saving a file in Illustrator (24.3 macOS Mojave) it looks unsaved. But it's not, it actually saved. But if I want to close the file Illustrator asks me if I wanted to save it, even right after saving. 

It's really annoying, and sometimes it's a real problem that I don't know if I modified something or not. 

Thank you,

Where do you save files?

Does it get better when you disable "Save in background" in the Preferences?

Thank you Monika! Disableing "Save in background" helped! 🙂  Saveing to NAS or to my inner SSD the same.

Anyway this means "Save in background" has this bug. But I can live without this feature.
