"Merging" different wall types.

[Keith_K]

Yeah, I tried that and experimented with various main layers on the walls that have more than one. It seems to be the walls that actually only have one layer that do the "bleeding" into others. For example the fence and the l-shped wall which you see on the screenshot below have been now replaced by a single layer stone wall and I have even used a dark brown colour to depict the wall on the plan but they still do exactly the same thing in exactly the same places. Trying to drag them away to meet where they should doesn't work either. The blighters just spring right back.
