I want to move a part of the tracks to the next mountain.
So I selected the top layer of blocks:

When I tried to cut them out, this was the result:

And this is the result if I select the complete mountain before:

Somehow the macro block selection and cutting is difficult to handle, as soon as there is mountain involved

Now I observed that even I'm on top of the mountain, the macrobloc selector is on ground level.
I have to raise it one or two levels to be able to select the parts on top...
It seems there is also some kind of distance effect ("LOD"), or depending on the viewing angle, I can see the selected and not selected blocks more or less good.
It would be good if the road blocks which are really selected get orange color.
