[NotAsSolvedAsIHoped] Items under stilted foundations issue

Edit: The issue is back for small items even with me removing the foot print for them. The large coral rocks work. The smaller individual coral pieces are still snapping to the above floor.  

I know it's possible because I have a few liberated boulders from Cats and Dogs that I can do this with but the few things I have liberated myself they always snap to the house floor. I have looked through the warehouse tab several times and compared 3 different objects and for the life of me, I can't figure out what controls that behavior. I have some build ideas but I need the objects to stay under the foundation. 

Edit: I figured it out! I will leave this here in case someone else wants to use it though. If you want to place anything under the stilted foundations and in the water with the new expansion pack you have to remove the footprint completely. After that you can place objects under the house and in the water. Now I have a lovely coral reef right under my little Sulani home.
