Missing unlocked req weapons in warzone

Started up a game and lost at least 3 unlocked weapons, all my level 3 BRs and level 7 DMR, didn’t even look at ARs. Has anyone else had this happen? I’ve heard of missing REQ packs, but not weapons yet. Any suggestions or help?

Sign out of your Xbox live profile sign back in and give halo about 1-3 minutes to load your data (req points,Spartan rank etc).Hope this helps only had the issues of it saying "retrieving fatal and stuck with the AR and magnum.
