I loaded this mod for my single-player game, because I love the concept. Then, to test the quarry, mine and lumbermill, I entered Admin mode and spawned the items into my inventory. When I tried to place these items in a large, totally flat area, I received the message "not enough contact with ground". So, I lowered the quarry until it was almost entirely underground. The message disappeared, and I was allowed to place the quarry. Then, I tried to pickup the item ("Pickup+" mod is installed), but I could not select the quarry. I switched into ghost mode to see if I could pickup a node underground, at a lower point on the quarry structure, but I still could not select the quarry for pickup.

Is anyone else having these issues?

The mods I have installed which conceivably may be causing a conflict are:
Less Building Placement Restrictions (LBPR)
Exile Lands Placeables
Stone Statues
Lemurian Architect
WYSIWYG Wheel of Pain
