This message shows on my tf2 loading screen(The one with your performance report) when I compiled my map. I tried restarting but that didn't work. So how do I fix it?

Same thing happens to me, I actually made a post about it. You have to compile the map and launch the game manually. Then load it from there. It is some bug on Valves end that was introduced somewhere in the February-ish patch, not really sure which one.

Leme know if you need more details on how to manually run the map.
