Well apparently it does not update the stats when host leaves. I will have to see if the theater has the full match but last night playing S&D I went 11-4 where we had a host migration when I was 5-4.
On Elite this morning my recent games shows 5-4.
We actually had 2 dashboarders, one when we made 3-2, we were down 3-1, and the other in the OT when we launched 2 predators, had 2 care packages and a UAV. Within the first 15 seconds they were down to 1 player alive, guess what happened?
Again I will look at theater to see if I can prove it, BUT I know this is what happened. And I remember being at 5 and getting my UAV, Care package and pred in the round that tied it at 3 which put me at 10 and gave me my streak rewards. I got one with a predator and didn't have a chance to set my care package.
