Don’t know if this has been posted before but I couldn’t find anything.
I’ve had this problem happen every so often for a long time. When I unlock say level 3 reqs and I go to use a battle rifle or something and replace the pistol it doesn’t register, it just loads me in with the pistol and assault rifle no matter what I choose. Exiting to the home screen and closing halo, then restarting it seems to fix it. But having to go through a whole warzone with a pistol and AR sucks. Anyone else experience this before?
