Nostalrius Begins - Quality wow vanilla realm (1.12)

Dear Nostalrius staff,
My Aquementas quest was affected by the continuous server rollbacks of this afternoon; I can no longer open/loot the quest container needed for the quest and can no longer progress past this step of the quest chain.

I have killed the NPC needed (Aquementas) numerous times and have always had to repeat this step due to server rollback canceling my progress. After realizing I could no longer open the container and fearing the quest had bugged out I decided to abandon it only to retake it shortly after. Alas, the NPC J.D. Collie in Marshal's Refuge is no longer marked as a questgiver to me.
Is it possible to take me back to my previous quest (Aquementas) while unbugging the quest items or am I doomed to never receive my healing offhand?

Thanks for the attention

Quick little update: there's no need to investigate this issue anymore. I was banned for mining thorium a few times more than I should have to verify if it was actually a bug or a very deep mine. It's really frustrating how Nostalrius staff decided to deal with an issue they created on their own by messing up (perfectly excusable - straight up banning what I think was probably 99% of herbalists and miners on Nostalrius, absolutely not).
