Serpent Queen Disappears During Fight, Causing Player to Be Stuck in Boss Area

While fighting the Serpent Queen in the designated boss area, the Serpent Queen suddenly disappeared mid-combat. After this occurred, I was unable to progress or leave the boss area. The following issues were observed:

- I could not exit the boss fight area.
- Teleporting to other locations (e.g., waypoints or town) was not possible.
- Logging out of the game and logging back in did not resolve the issue; my character remained stuck in the same boss area.

Same today for me!

I have done that same boss many time before never had this issue!

I hope the instance close and I can get out!!
