I got this problem outta nowhere.. I was workin on my map, while i was workin i forgot that ill have fullscreen game pop on.. And it froze radiant and it crashed once i went back to continue my work, the map got deleted and the backup too it's like it got restored from the beginning. Is there a way i can get my map back or it's gg?

Wierd shit. But 90% no you can't if you can't find it in map source folder then sorry no.

This wouldn't "delete" the map - max it would do is corrupt it so something else must be up
