Anyone else having this issue right now?
I have the exact opposite problem. My stats got blown way out of proportion. According to Waypoint my most played day has something like 100 days worth of playing time on it. I had 2 matches (one on Abandon and 1 maybe 2 on Complex) get multiplied over and over for some reason. I’ve tried everything on these forums to get the issue resolved but nothing has ever come of it. I miss using halotracker. 
Yeah, my stats haven’t updated all afternoon.
I have just moved from grifball to flood and my stats aren’t updating either, I’m keeping count as I am aiming for 1000 war games. My in game stats are frozen at 913 games and waypoint is frozen at 762 games?
Trying for 50 CSR in flood but I can’t see my progress … smh.
