I started as a Blood DK in Legion Remix, when I went to go do the Unholy Artifact questline I noticed after the first quest I didn’t have a weapon (the blood artifact weapon appeared as broken) so I used my Death Gate to go back to Acherus and then back to Dalaran to pick up a “Timerunner’s Greatsword” so I could do the quest. When I returned to Acherus there wasn’t a portal to Duskwood like there originally was. I have no way to get to Duskwood as, unlike retail, I don’t have access to most of the world. I abandoned the quest in hopes a portal or quest would show up but nothing appeared. I am effectively softlocked for the artifact questlines. I am hoping this will be fixed soon as I would like to do everything in Legion Remix.
EDIT: If anyone is also having this issue I found a workaround. When Moratari gives you the quest “Extracurriculars” you will be prompted to do the Legion starting scenario and subsequent quests afterwards. You are asked to go witness Dalaran being teleported and when Dalaran is above Deadwind Pass you can fly down to Duskwood and continue the quest line. Not the fix I was looking for but the fix that works.
