I have discovered that the gametype key does not appear to work on a func_bobbing entity. I am testing Spacestation Beta 6, which has two different platforms in the same place with mutually exclusive gametypes (there is a hole in the floor that is filled in except in CTF, and a func_bobbing was supposed to go through the hole in CTF but stop short in other gametypes). Both platforms appear and it causes trouble.
