When a hero visits a Magic Well, say located at position 20-25 on the map, all the Magic Wells on the map are considered visited by this hero for the current day.
It would be better so that each Magic Well to be considered independent, so the hero can visit the Magic Well located at position 20-25, to replenish all his spell points, moves to another Magic Well located at position 30-35 to replenish all his spell points, and this the same day.
The Artesian Spring is a two squares location. But each square of the location acts as if it is independent. So the hero can get double his maximum spell points twice at the same location.
It would be better so that the two squares of the location to be considered as the same location, just like the Standing Stones, so the hero can get double his maximum spell points only once.
In addition, just like the Magic Well, all the Artesian Springs on the map are considered visited by a hero when he visits one of them.
Here, too, it would be better so that each Artesian Spring to be considered independent, so the hero can visit the Artesian Spring located at position 25-30, to get double his maximum spell points, moves to another Artesian Spring located at position 35-40 to get double his maximum spell points, and this the same day.
