As to where if it is spawned in under a faction, as if there is some sort of living essence within the UAV, it can then be controlled, and toggled with. This is a serious glitch that needs to be resolved.
Also, say, someone does spawn it under a faction in a server, but that UAV gets destroyed, it spawns as empty. So even though you got the chance to use it ounce, it was as if there was no re spawn because you can no longer use the UAV, because it is now empty on respawn.
