Whenever someone leaves a fireteam, it moves that fireteam to the top of the list as Updated x seconds ago. This moves posts that are hours old to the top of the list that other people now join and then get frustrated that they aren't getting invites, leave the fireteam, and then it starts the cycle all over again. This happens all the time and is extremely frustrating. I know that the answer is to "Close fireteam" so that others cannot join. But no one does it, so the fireteam finder is just a constant mess of old posts. Please fix.
