Door won't open in the Palace map to the next area of the map.

I'm just doing regular mapping, and come to this door that refuses to open and seems to glitch me back when I try to continually run into it. No idea what could've caused this, bricked the map.

Same just happened to me, so bug is still active though never seen it before.
Weirdly another door also wouldnt open from one side, though I was able to go round the other through connecting rooms and open it to go through.
After going through it once though it wouldnt let me go back through it again in either direction.
Bricked map and I will avoid Palace in future
