Hello.
I'm still having this problem. I eve tried to start from the autosave that I got from going into that place...
Tried relaunching the game etc.
Have all recent updates, no other additional mods...
What could be wrong?
Btw. When that platform is going down I also see a bugging character (that woman that I have to speak to) and when it goes down at first I can't enter the platform at all, by loading the save I can enter it but I can't use the lever ;(
Never mind -_-. I just found her now bugged a bit into the wall, I was able to speak with her...
I think this was a ment thing by the devs to find her there
