(adsbygoogle = window.adsbygoogle || []).push({}); when i am playing online in example survival on town just as i start doing good the host leaves and ends the entire match this is annoying because i have been trying to rank up to the knife but i keep getting backed out

It has been like this since W@W, people leave all time, whether they leave bc they are pissed off or have been invited by mates, people will always leave.
It happens all the time

I dont think it will change, no matter what implementation they use to keep matches open.
Its just one of the downside to zombies, One good thing about this time thou is that your kills/stats are saved in real time, so on the up side you dont loose these if the match ends (which helps your k/d ratio :p).
The best thing to do is to only add friends who dont leave matches out of rage, (thats what i do) its a bit of a pain but well worth it,
If they are good players and dont leave makes it way better

True didnt know the stats stuck after it ended

ye man try it on a quick test game.

Log your kills before a match
Have a quick test game say 20 kills then leave, go check your stats again. Should go up by 20.

This also works for custom matches

happens to me aswell
