Steps:
1. Today, I tried to annul my marriage only to find out I must have been able to discard the ring somehow. I can 100% verify it is not in my inventory, it is not in my retainers' inventories, nor are any of them wearing it. I also typed "/isearch eternity" and had the ring linked to me to be 100% sure.
2. I know it seems impossible but I can't find it and there's no way myself and the system overlooked it multiple times.
