So i was creating a map since like 1 month ago and everyday i open up Hammer to do some progress on it, today i just did the same, open Hammer and load my map, but now i got this, all my map elements are gone, i already tried decompiling the most recent .bsp file to open up on Hammer and continue, but it didn't work.
