Castle Nathria - Stuck in loading sewer pipe

In front of the Hungering Destroyer there is some sewer pipes. If you go in one of them in the middle right at the end, you get stuck in a loading screen. After a very long while (abnormally long), you get remove from the Castle Nathria from the back entrance in the sewer mouth.

I can give a more precise locations with a video if devs needs it.
3 people in the raid try to repro it with me when I found that out, they all had the same problem
