showing the wrong movement arrows because the MP are lost this way. Now if also transport movements (and strategic movement) follow the same pattern then it's a heck of a problem.
MP are not lost this way. Please be aware of the rule than a transport can move into a region with another unused&unmoved transport with no movement cost. It is a free move, the "slide" I referred to before.
The autoselected routes you show are actually the unintuitive but arbitrary selection out of 2 or more equal choices.
That is why sometimes transports can move much further than 7MPs suggests, when they can exploit preexisting transport chains.
Check the manual on transport movement.
In my view, it would be nice if this were improved to work more intuitively, but it is not worth the effort/risk to make the code change. I know that I am now so used to it that I don't think about it anymore.
