I was helping guide a new BM player after our win and we were still inside the map. He told me he was being pulled into his Team Up in 30 seconds.
Had his Team Up started during the game, he would have gone Missing.
Another way someone might go Missing is accidentally porting to their Marked Location.
Maybe others reading this can confirm other ways one might go Missing (other than the typical disconnect).
Can it happen if someone is in a PvP queue? What about someone porting to Commons or home by mistake?
I propose Beastmoon get a safety feature where it will not allow those things to happen.
Anyone who already started a Team Up should have a pop-up message saying they cannot join any queue while waiting for a Team Up to start. And porting to marked location (or anywhere) should not be allowed either (if already in Beastmoon).
