The Antiquarian Site of Power has a collision error?

I have rolled a new character and intended to finish the Antiquarian site of power before bed. So, to be clear, this is a fresh start in Online Mode. New map, new everything. I don't know if it matters, but I skipped the tutorial.

Get through the fight, got to the last chamber where the automaton boss spawns and instead of walking down the ramp I... float? The animation on my char freezes too. It's all jittery too, like I'm falling? Here's a video of what I'm talking about.

After making the video, I decided to restart the game and see if anything changed. The bug is still there and I cannot finish the quest.

I guess I could ask someone on the Discord or a friend if they will let me do the quest in their realm. Or create a portal to a new Abeyance and see if I can't do the quest there.

Thank you for your hard work on this game. There's a reason I keep playing.
