I was working through the Cataclysm quests and hit Firing Squad. Once completed Harrison Jones disappears and you can’t turn in the quest. A /reload doesn’t help, but logging out and back in does make him appear so you can complete it.
There was also a later quest, I think Schnottz So Fast, with the same problem. You can’t turn in the quest until logging out and back in.
Both of these quests have comments on wowhead documenting these problems for a long time but I didn’t find a bug report here.
I just ran into it too. I’m adding a link here for the Firing Squad quest and here for Schnottz So Fast so the blues can see just how long this has been a thing.
Now whether or not they’ll do anything about it… Eh…
Can confirm, once again, 13 months have passed (Cataclysm Chromie Timewalk leveling) and this is still an issue - actually, it’s MORE of an issue - I completed “Firing Squad”, Harrison did not spawn.
I logged out and completely closed the client. Re-started the game and logged back in and Harrison is still not spawned. In fact, even though the “Ready to turn in” flag is present, you can still walk back down to Schnottz’ hut and re-trigger the walk & talk & firing squad & rescue cinematic - to no avail, still no Harrison.
If only this game was run by a billion dollar, multinational company that had the sorts of resources necessary to hire a competent debugging crew to find and remove these issues in a quest line that’s 13 1/2 years old as of this post…
