Warcheif's Orders Bugged

I was doing the war campaign and I went to complete the quest for Nazjatar, when the loading screen for the cinematic showed up it disconnected me and put me into a Island expedition tutorial. Since then I have not been able to figure out how to get the quest back or complete that set. I did every single war campaign quest until now where its telling me I cannot continue until I complete those. I submitted a ticket but it says OVER 2 days before they will respond. I’m beyond pissed right now, I’ve been playing this game off and on for over 15 years and this is the type of crap I have to deal with now. Can’t even continue because of a bug or glitch or whatever it is. ANY help will be greatly appreciated with this and also, has this type of thing happened to anyone else?

Update
Managed to get it to some how work with a party sync. Still frustrated about how it had to be fixed/done.
