I can't go out from Realm of Shadows DK

A cordial greeting to the entire community, I come to tell you a story.

First of all I must say that I'm an *****.

I bugged my character and I can't get him out of where he is. I already used the unstuck from the website but it's still the same. In the quest Into the Realm of Shadows in the DK starting area, when I got off the horse after using Horseman's Call to summon Salanar, instead of handing in his quest, I handed in a completed quest to another npc, which resulted in me coming back to the realm of shadows and now the horse does not activate.

So now you know, when you get off the horse, turn in the quest immediately and don't do what I did when I went to turn in another quest

I already opened a ticket on the web and in the game, hopefully soon a GM can help me but I understand that there be quite a queue

Thanks to everyone beforehand

Edit: Solved. I just had to leave the quest, it took me out of the realm of shadows, lol :p
