I would have reported this in secret, but my private message couldn't been sent to fromhell. So please be fair, and don't use it!
The bug is, that you can rocketjump out of the map on CTF_Compromise and you can come back at the blue base with another rocketjump. You can see it in action on my demo:
http://udionline.hu/fajlok/compromise_bug.dm_71 . That doesn't work for the red base. I couldn't check, but I guess while you move outside the map, you are invisible and invincible, so it's an advantage for the blue team. Please check if I'm right, and fix it for the next release.
