While I've already made a post about this in the Bug Reports and Fixes forum, I'm also opening a thread, because it's a big issue and many people are probably looking for a solution.
In the current build of Morroblivion, there is a bugged .nif file that makes it so that areas in Dwemer ruins that contain an observatory are impossible to walk through. Instead, everyone is shaken around at high speed (click to download a short video of the issue [2.6 MB]). Arkngthand Heaven's Gallery, Nchuleftingth and the Galom Daeus observatory are examples of this.
To solve this problem, use this file. It contains an old version of the .nif file, and makes those areas playable again. Install it as any other mod.

Can you please provide an alternative link as the one you posted doesn't work anymore, and i'm desperate for this fix
Thanks for telling me. I have updated the link.
Hi. Is there a working link for this? The provided link no longer works.
