We were at the final boss phase during the Glassway grandmaster and I was kicked due to inactivity. We were past the 45 mins and lost our revives. I died and was viewing one of my other fireteam members and then was kicked due to inactivity about 30 secs before they killed the boss. I think you should review the qualifications being kicked. Now I have to run the whole thing over again as my other 2 fireteam members got credit for the GM when I didn't.
