First I was the commander of my clan and dropped for no reason and had to be reinvited as a soldier.
Now the clan wars patches and monster care package patches I have unlocked are gone and unavailable respectively. I had them for sure and set them as my patches. Now the characters I used still show them as their backgrounds but i cannot select them for my unused squad members.
Did you create a new Call of Duty account and link your game account to the newly created account? If so, link your game account to your original Call of Duty account and see if your items return. If not, try re-linking your game account to your Call of Duty account. When you were dropped as commander, did your clan mates still see you on the roster before they re-invited you?
