This is the third time this has happened and it really bothers me now. After i complete a warzone game ill have the usual stats pop up and i get my req points. But every once and a while the stats wont show after the game and it says there is an “error” and when i go to my reqs i have gained no more points. Also it sycks even more when u use a boost because you completely lose that too. Im hoping this is fixed but its not like 343 even listen to us.
You still gets those points. They just don’t show up immediately.
Yeah sometimes it just takes a while to load 
To me it doesn’t show up after the game, but when I go to the store it says loading, and then it shows the added points
If this happens it takes a bit of time for the points to get added, don’t fret, you still get them.
