Working on a new map. I compile the map and run it every five minutes or so just to make sure everything's going alright. Recently I added a few brushes, objects and overlays, saved, and ran the map. Much to my surprise, however, Hammer did not compile any of it and instead I was playing in an earlier save. Therefore, none of the aforementioned things I added were there. I'm not an expert at anything to do with mapping, so I have no idea what's going on. If anyone can help, thanks.
