So,
I was pumping some BGs after work and after my client crashed I received notification "World Server Down".
As soon as I logged in I noticed that it is only me that crashed and that I don't have deserter debuff.
The thing is that I couldn't que for Bg anymore on any toon from account, dangeon finder works, but issues with Bg que didn't go away for 1 hour.

If anyone have some solution for this I would be thankful.
Have a good night.
Milan.
