Detailed steps on how the issue occurred.

The quest says I have completed 2/12 copper rings. I have 12 in my inventory. I don't know why it stopped at 2 and I am not sure when it stopped as I wasn't looking. I've tried logging out, abandoning the quest, etc but it just stays on 2.

Extra: I have noticed that someone from another server has posted the same bug report at the end of last year. Evidently it's not been fixed which is why I have posted a bug report myself.
