If nothing's spawning in, that's probably an indication that either your logic outputs to spawn the flags are bugged, or you're trying to spawn flags with a point value of 0, which the game automatically removes.

I know this was stated in the original thread, but a possible cause of point value being 0 is setting the flag to the wrong gametype - it has to be Player Destruction or Robot Destruction.
