The targetname of that one is 'stealth_uav' because it uses the pegasus model. The error itself is saying the owner/player is still in the game, I think, but not on any kind of team. I am pretty sure the only way that would happen is if the owner is spectating but not part of a team. Yellow on the scoreboard. In game terms, if a player is on a team, there are typically three possible states the player can be in: playing, dead, or spectating. Which is different from above. The last one is typically when the player is dead but hasnt respawned yet. Say if there is a respawn delay or the player is watching a killcam. Or spectating in overtime but still on the team.
