I am returning player, last played was Shadowlands. I went to NW to do a dungeon but everything on my map was reset. I still have the achievements from when I played, including “Explore Bastion” but yet my map is blank; as if I had never been there. All of the quests have reset, despite previously completing all of it.
Not usually. You should have retained the areas you explored. I don’t know any way to resolve that issue without going out to explore it again.
You did complete the Shadowlands Campaign, as well as the Kyrian one on that character. You appear to have completed up to “Our True Purpose” for the Venthyr, and “The Endless Forest” for the Night Fae.
You’ll definitely want to submit a bug report though so our QA team can take a look.
