I can be tp'ing to a /home or outpost or wherever, after I TP, i am removed from my team. any idea?

not really sure what plugin would do that but it could be using a hook provided by this plugin and removing from team when that is called.

OnPlayerTeleported(BasePlayer player, Vector3 oldPosition, Vector3 newPosition)

you can search a partial match for OnTeleport too. otherwise good luck
