There is a small area in Maj’Elka (Imperial Era) that is shown as accessible on the minimap but cannot actually be entered by the player, neither by foot nor through teleporting (tested with Mage).

On the screenshot, focus on my character first. Then, “switch” your eye to the minimap view and look at the two combined rectangles on the minimap to the left of my character. That area is inaccesssible, yet the minimap shows as if it is accessible and can be entered.
Either the area is not intended to be entered and the minimap layout is false or that small passage to the top right of the area is supposed to be accessible and not “cut” off as it currently is, as seen on the minimap. If I recall correctly, the area in question is close to the entry point to that area, but I could be mistaken.
