Ok so this may sound like i have no idea what I'm doing but trust me i do know what is going on. So when i try to re-compile one of my maps, after making changes, it compiles. But when i load it up in game nothing has changed its all the same. Then i tried to copy and past the map into a new window and compile it from there. But it does this: Then i restarted steam and it still came up with the same error on the new file. I compiled once more on my updated file but it didn't compile any of the changes. I don't know why hammer wont compile my map.
