Playing the Raid last night, the team made it to Aksis Phase 2 as so many groups had, and like so many groups is when turmoil begins. Teammates begin dying and making trivial mistakes, and some members become demoralized and leave the team. Then two random squeakers we were running through... let's call them Bob and Steve for reference... begin to become obnoxious and we decide to remove them and find new members. So we kick Bob and all was well, but when we went kick Steve it said he left the Fireteam, but Steve was still in the game with us. We thought it was just delayed at first and it would remove him eventually, but after 3 minutes Steve was still there and able to emote, run, shoot, and function normally. And because he technically wasn't apart of the Fireteam I could not kick him again. So I decide to bring the remaining three team members to orbit (which is a shame as we had the Monitors) and leave Steve behind. This is where things get more interesting. I invite another friend who had just got on... Jim... but when Jim tried to join my Fireteam who was sitting in Orbit, it put Jim into Steve's game who was still in the Raid. To make things even stranger, Bob was apparently trying to re-join Steve only to get put back into my Fireteam still in Orbit waiting for Jim. This went on for about 10 minutes mainly out of curiosity before we decide to reset the game and go from there, where the bug was fixed and we able to join up normally. It just made for an interesting tale to tell.
