In order to complete Ashenvale Quests, my last questline was "The Diplomat From Silvermoon". This is supposed to start with Sheelah's Last Wish, but in order to receive that quest, you must first complete Security!.
Oh, but to get "Security", you first need to do As Good as it Gets. This quest is given out by [npc=33889] at (82,53) in Satyrnaar, Ashenvale.
In order to find Krokk, you need to toss [item=45710] into the smoldering brazier at that location. Problem was, I no longer had the powder. Not sure where I used it, or if I discarded it, or what happened, I don't remember.
You are supposed to be able to talk to [npc=33837] to get more, but all he did was said "Blood and Thunder" to me in his dialogue box. I tried logging out, logging in the next day, reloading, going back to where Krokk was supposed to be, etc. Nothing worked.
I finally opened a ticket, and within 24 hours, a GM had sent me a bag of powder, along with this message:
Not to worry, we have seen this pop up a few times, and I can confirm that our devs are aware of the issue. They have allowed us to send out the powder to players who are stuck. You will find the Secret Signal Powder in your mailbox shortly.
I don't know if anyone else has had this issue, but I was really frustrated because there was no info on any of these quests related to the problems I was having. Hopefully, if you have had these issues, this will help you.
