Loosing zoom on scopes

Yup, same thing happening to me every game. Any time i reload, use an ability, change weapon, etc, when i return to the sniper rifle and ADS it does not zoom even with the 6x scope attached. The only way around it is to switch the scope to another scope, wait for the rifle to reload, and then switch back to the 6x scope and wait again for the rifle to reload before trying to ADS again. This has ruined gameplay several times now as I'm mid firefight, have to reload and suddenly lose the ability to zoom and find my target again and i get killed while trying to fidget with gun settings mid fight every game.
