And regarding movement... is the required number the one shown by the green bars? If so, I would never reach the displayed end of the movement if I had diagonal movement options. Maybe you mean that only 100 MP are required to take an object? Then everything makes sense, but I read everywhere and checked myself that it is exactly 141.

The required number is the minimum number of moves required to perform the action.
In this case, it is indeed 100 MP.

In the Physics section, on the page about logistics, there is a subsection, I don't remember the exact name, something like "features of the last move" or something like that.
If you checked and it was different, please upload the save file.

* On penalty territories, the required number of moves is different, even if there is pathfinding and all creatures in the army are native.

PS. IMHO, there is still something that can be tested here - the number of moves that is reset to 0, depending on the presence of a penalty, may be expensive and others.
