I only experienced this in the hospital on top of the hill next to the new chairlift.
I could only close one or two side doors which have been open but after this i could not open them anymore. the same for all the doors inside. the second pair of the main entrance doors also did not open nor closed(couldn't test that).
So i was unable to use the staircase and check the upper floors, since that double-door also remained closed.. the notification to open the doors did not even pop up. like they were just not featured.
