"Can the last person to leave please close the door behind them?"

Typically the randomly assigned party lead will initially click to refill the party if say a tank bails. Now you cannot reverse this decision so after 10 mins or whatever, the leader is suddenly the only one left in the instance. They leave which would normally terminate the instance...BUT...it pinged you to enter In Progress before the last person exited. In the 5-10s it takes for you to hit Commence and load in, that person has zoned out and your arrival has caused the instance to persist. There's not a whole lot SE can do here.

Actually, there is a way to stop the searching. I've done it a few times, but it's been a while so I can't remember exactly what you do. I believe you have to click where it says searching and the box pops back up and you can hit cancel.
