Connection loss / Losing game data

Recently I've been trying to increase my "kill" rank and I've experienced a large amount of quitters. When a host quits, the game ends immediately and it appears that all game data is lost. I was wondering if perhaps the leader boards just update slowly or if I'm correct on the loss of data. I understand the difficulty in saving the data as time passes, but, is there any possible way that even through the quitting of a host the match settings would be saved?

I 'think' I'm right in saying that data is saved at the end of a game, so I beleive u are in fact losing data. This wouldn't be too bad if it weren't for the huge amount of quitters and poor quality of host migration which I believe to be being fixed atm.

im not sure but a good way to check is to get 1 kill in a match then go to ur locker room and if u have 1 more kill than before then u are still gaining data even if the host leaves. imma check that myself in a bit later tonight. good question thanks for the thought.
