Really weird problem help plz

If I understand correctly, your .map files are gone?

If so I think you have the same problem as me.
When saving .map files in a folder or something, they disappear after computer restart.

Whenever I'm making a new map I need to save the .map to my desktop first.
Then I can move it to another folder later.

Somehow I think windows treats it as a suspicios or possible-damaging file(I don't know, I'm guessing.) so it removes it.

Anyhow tell me if it works saving .map to your desktop first.
