Halo 5 Req system failure

I have been playing Halo 5 for the past few days with no use of any of my Reqs. I have tried everything even uninstalling my game and reinstalling it. Its not my internet so whats going on?

You have had your REQ collection taken by the Guardians.

It seems to be a bug in the game, try playing a quick arena game mode. That usually fixes the problem for me.
