Grega, I've had to correct you just as many times.
For instance, The Team has dubbed CTDB mode experimental. They did it, it wasn't the public. Therefore it can be safe to assume it is loaded with bugs, which it is.
It has been known to cause crashes. The dragon doesn't always show up for some people. DragonBalls have been known to simply not respawn. The immortality wish is a joke. DragonBalls can be thrown off the map. The scouter still shows DragonBalls if you change maps after just being in a CTDB gametype. The list goes on, but that's only because the game mode itself is experimental.
I think it's for all these bugs that CTDB mode is not available on most maps. Afterall, why exclude something if it works so well?
