ctf haarp is now an official map, many maps we have hosted in the past are! However, the filename for ctf haarp is the same as the old community download version, trying to play the official map will cause a file mismatch and kick you out. While we are not yet running this map on our rotation due to this issue, you may encounter it elsewhere. If you think you've played it before on a community server, look for tf/downloads/maps/ctf haarp.bsp and delete it!
