The Unseen Blade - Bug

[Onetruelove-sylvanas]

Hello! After 3 tickets and 2 bug report, i still have this problem!
Done all 10 Stage from The Unseen Blade (Rogue) quest.

• got Kingslayer blades
• got Kingslayer name
• finish Stage 10
  After this, quest reappear in my quest list
  Now I can’t finish the quest because at Stage 9 I can’t pickup Kingslayer Blades becaute I have them in my bags but the main problem is:
  -> Every time I go to Stormwind by foot, air or heartstone, after 2-3 seconds I’m teleported at the entrance of the Stormwind starting Stage 1 from The Unseen Blade quest and I’m attacked by guards.
  -> If I use portals to enter Stormwind, I fall from the map and got disconnect. When I login again, I’m at entrance of the Stormwind starting quest again from Stage 1
  I can’t abandon quest, I can’t enter Legion dungeons because game don’t see that I have Kingslayer weapons (Artifacts) and I can’t do any quest from / in Stormwind!
  All this after game auto added again this quest.
  No problem with other characters.
  How to solve this weird situation, anyone know?

I am having the exact same problem. I tried just doing the whole scenario again but I am unable to pick up the weapons as I already have them.
I have no clue what to do and can no longer enter stormwind without doing this scenario…

I managed to fix it for myself by going to dalaran and handing in the quest to the guy in the rouge underground room. Was then able to go into Stormwind freely.

What’s bad is they still haven’t fixed this, I did it today and can’t hand it in, the NPC as well as the other two quest givers just don’t spawn in, contacted blizzard support they provide literally nothing (to be expected by this black hole of a company), the fact this expansion came out in 2016 and this sh1t isn’t fixed is a disgrace lol, don’t even see point of paying £10 a month for it if they don’t care about their fan base enough to fix a massive bug that locks me out of a lotta shizzle
