Ores cannot be mined due to changes in the pathfinding system.

In version v1.1.0, due to the optimization of the villagers’ pathfinding system, they are unable to pass through grids with steep slopes. As a result, mines on mountainsides and peaks are completely inaccessible and cannot be mined at all. The terraforming system cannot level land with large slopes either, because the villagers cannot get there, which is simply baffling. I spent the whole afternoon trying to carve out a path to the mountainside but failed. A huge number of mines are just there for show. The experience is extremely poor.

Is this mainly near the edge of the map? Meaning, you can select an area very near the edge of the map but then the villagers can’t get there?
