Dawnbreaker boat(s) not there

For mutiple runs, but not all of them, sometimes the big Dawnbreaker boat itself is not there at the start of the dungeon. Visually it’s already floating before even going on it.
Today during Mythic run, both small boats were missing for me. Reload did not help.
Somehow the team managed. During the second boss fight, the yellow orbs weren’t there either.
The entire time the minimap is showing different locations for the boat.

It’s not just a graphical glitch, everything is then broken location wise.

During M0 this wasn’t much of an issue, just go out and in again. But now that M+ season has started, this is a waste of time and not an option.

Am I somehow the only one where Dawnbreaker dungeon bugs out?
