Today, I finished a game with zero deaths and took a screenshot...25 seconds later we had three deaths added to our vehicle squad (one of our guys died in the game but then it jumped up to 4 deaths total). Strangely the total ticket loss count stayed the same (103) but the tickets we had left at the end of the game dropped by 6. This was on 44th Server 1.
The same thing happened yesterday on a 44th custom server (as we had a clan match) and our MBT survived the whole game without dying (at the end of the match we had three deaths added - one for each player).
Perhaps the strangest thing is that today one of the players in our Squad did NOT have a death added (Gears).
We were all in the tank as the game ended and nothing changed in the background while the game was ending (didn't hear vehicles getting blown up or anything relevant).
Attached below are the screenshots from today.
