Hi GMs, I am facing an issue with the Rogue Poisons quest which I accepted from Shenthul in Orgrimmaar. I abandoned it, and was unable to accept it again as Shenthul does not offer it anymore, leading to my rogue having a serious problem in the form of not being able to create poisons and I am in need of a solution. Please advise me on whether some sort of reset can be applied which would enable me to re-do said quest. I would highly appreciate your prompt response. Thanks in advance. Regards

Many thanks for the response. I did create an in-game ticket before posting here and I am waiting for a response.
