I have been trying for some time to place it, with no luck.
I have attached a screenshot of how i usually do it, i have also tried placing it a little deeper into the gray zone and a little more into the house floor, still no luck.
Have tried staying exactly at center when placing, still getting the "you cannot build that there" message, if i move really close when trying to place it doesnt even say anything, just bumps the character a little.
I have been using ctrl to detach it, and shift to rotate it exactly right.
Any help and tips would be greatly appreciated.
