This is the third time in some weeks that I've had this bug. I go in to fight Kindlord Rilis, the last boss in The Banished Cells, and as soon as I attack I get bubbled. Normally the Bubble only picks you up and drops you from a short height, but for the last few times it has taken me all the way out of the map to the top of the skybox and dropped me on an impassable ceiling and I can't get down. And then you die from fall damage. It's impossible to jump back down because you're stuck on some kind of invisible platform. I can't loot, can't be resurrected by my team, they can't even see me. And I have to wait for them to kill the boss before I can resurrect myself, break team, and then use the leave the function or teleport to a guild mate to get out.
Attached are images of this time I did it.
All of the times have been in a random normal dungeon farming transmute crystals.
It has happened on two different characters for a total of three times in the last two months.
I'm assuming it's a desync issue, because I'm playing on quite a high end PC with ultra graphics settings.
I just wanted to bring it to the teams attention in case it was not a known bug. It's happened to me pretty often lately.
