There are, in my opinion, a few serious issues with this Collection achievement (Redeeming IG-6417). In order to get the ascended back piece, you have to get a series of recordings. There are multiple issues with this:
1. You have to do the Domain of Vabbi meta - been on for hours over the past several days, and the maps never seems to do it. Have checked Looking for Group as well. No luck
2. You have to complete the Sandswept Isle meta so that you can do the fishing event. That, too, seems to never be done.
3. The one I am inexplicably not been able to do is the event "Stop the Zaishen from desecrating the Temple of Kormir" event in the Crystal Oasis. This event NEVER seems to spawn. Ever. There doesn't appear to be a trigger for it. It either happens or it doesn't.
Specifically, with #3 - does anyone have any ideas?
