{POE2} no path in maps

Good evening,
i just happened to run into this issue where i found a citadel that has not path going into it. At first i thought well maybe i cant go through the top and the path that leads to it is in the bottom of the map. So i spend a couple of hours to find out that there is no way to get there. Not sure if anyone is having similar issues.

The same problem with shlter
