Potential bug when crossing a stream without a bridge along a road

[Plain Ian]

The recent discussion about movement points got me thinking and testing, and I think the following situation might be a bug.

I ran the test in France '40 because I needed units that would have MP's left after crossing into a village hex and streams with and without bridges.

It's no bug. In the situation on the left, the unit is looking at a rickety foot bridge into town. They can't use it, so they have to go around the bridge and into the village, likely through side streets that aren't optimized for mechanized units to move through, thus 49 MPs.

In the second situation, the road crosses a stream before going through town. This allows the tanks to cross the stream and then enter the village via its main street, thus only 23 MPs.

Well this descriptiion of whats happening sounds about right except that in the first case the game engine says that despite the bridge being rickety and non useable they re still charged 1MP for using it?
