all parts are connected & i'm stood next to the area, there seems to be a limit to how far it will copy upwards when door frames are used.

foundation + 9 doorframes high +windmill is not being copied above the 3rd

Have you tried increasing radius?

I had to take it to something stupid like 9 , but then it started picking up other crap around the base i did not want..

Suppose that will have to do, then i can clean it up....
Just surprised it wont pick up items connected directly.... to the foundation next to where i stand, the door frames have nothing in them...
