req points not adding up right

I don’t know if anyone else has had a problem with losing req points but I sure have. Just finished a warezone match I had 469653 req when I started, I finished a mastery for 2500, a kill mastery for 1000, and 2123 req point for the match. My new req should have been 475276, instead I got 471771. I got screwed out of 3505 points, I think this is something for 343 to look into, and everyone else to keep an eye on there points.

do you mean xp? because you only get xp and a req pack for mastery or when you have lvl 3 and 5 are completed.
