I'm relatively new to mapping in HL2...I'm not even sure if this is a HL1 or 2 board, but the editor's the same anyway, so here goes...
I started a map, worked on it for hours...and periodically compiled it, and ran it to do a test run and see how it looked...it was for HL2 deathmatch...
I kept saving it now and then over the same name, and my son went to do something after I saved the map, and closed the program...but, when I went to reload the map a couple hours later after he was done...the map went back to what it looked like so many hours before...
What do you think I did wrong...? Is this something that can happen?...or did the map maybe save somewhere else...
Any help would be great...
