Recently I was playing with a friend. He came to my world and beamed to my ship, and for whatever reason EVEEY CREW MEMBER from HIS ship is now in MINE. I can't use them or dissmiss them since they aren't on my crew, and I've tried dumping lava and poison in them but they refuse to die. They are annoying, they're making me lag like crazy on my ship, and they're allways in the way. Has this happened to anyone else? How do I get rid of them.
