When building terrain tiles (placing trees and other clutter) if you use copy you will get the same error as if you were placing objects on "slice" lines (when you press build it will take minutes to build the tile and you will get a message with int /number of objects here/).
You have to manually press add for every new object, which can be very time consuming.
I wrote about this before and it is still not fixed.Hope to see it fixed soon.

EDIT: Hmm what i found that it's not the copy that is making this problem , but rotating the clutter!!I will be able to copy multiple objects, but still being unable to rotate objects is very very wrong.
