Preevents for the Branded Devourer Queen are bugged, and I’ve seen posts from more than a year ago that say it’s always been like that, AND YOU LINK THE TIER 4 COLLECTION TO THAT EVENT? Seriously!
I’ve been trying to find a map there that is not bugged for 4 days in a row and the NPCs do not move from the place they are stuck.
Either link the collection to something else or fix the bug cause this is embarrassing for you and frustrating to everyone trying to finish the collection.
