Fireteam Status Has Changed

Is anyone getting that annoying error every now and then where your in a middle of a game then all of a sudden its just like “Your Fireteam Status Has Changed” back to the menu you go. I am not in one half the time and last night I was quite annoyed as I got myself a Legendary XP boost and lost it because of that. It can also count as rage quiting and it isn’t my fault at all. I have no intention to rage quit.

It happened to me once or twice i think its when a someone in the squad never resets halo but just leaves it running so to speak when they turn off there xbox you have to go home hit start and hit quit game to fully close it
