Notification - Party Leader Quit

I had the same issue where my premade squad and I had just killed another squad and we were looting or rotating to another area when i got the message "Party Leader Quit" and was sent straight to the lobby. Happened in 2 different games through our night. If i had to guess we maybe played somewhere between 20-30 games and it only happened twice. Just messes up their game since my othwr 2 players were still in the game and were now down 1 player.
