kk i put a foundation down and bang down a tc

take 2 steps away so the new foundation is not connected (but its still in the tc zone)
Now i place foundation - add door frame then add door

Sure enough when entity cleanup runs - it takes my door
yet it does not remove any placed deployables i have on the ground (because they are in the tc zone)

So why is it stealing my doors ???

it looks to me like the foundation has to be connected to the foundation with the tc
regardless if its in the tc zone or not.
