Macaw's Fences and Walls suggestion to connect vertically stacked walls like in vanilla

[Acenio]

I'm suggesting you extend walls upwards if there is another wall above like vanilla does with its walls. So in the picture below the bottom modern sandstone wall would extend upwards to connect to the railing sandstone wall.

Added it for the modern walls, might later add it to the railing wall too
