Situation #3, which simply stunned me %) (I've attached the save file).
Again, it's a balance issue. In situations where bugged passages are generated, I can more or less navigate. But I haven't encountered a situation where there is no passage at all yet. I spent a very long time wandering around the game and trying to find it, because I was sure that there must be a passage.
Zones:
(1) - my base on rocks
(6) - dungeon to the left along the road
(7) - flax to the top along the road
(3) - flax in the center
(4) - Necropolis in the center
According to the map, there should be a passage from zone (6) to zone (3), but there is none!
Also, I was very confused by the guards in the screenshot below.

The eyes and hounds don't guard anything at all. And there are quite a few of them, it would look like guarding a passage, but there is no passage.
