Question: Can a Shipyard be placed on a series of foundations under water? Has anyone tried this?

Dont know if u can before you place it down , but i do know that if you place a pillar under an existing one , the shipyard wont allow you to build a ship in it.  it says something like shipyard obstructed cannot build boat.

Same error if you place your shipyard and there is  any pillar somewhere under the shipyard, it says something like shipyard obstructed cannot build boat. Luckily it was an ally pillar I got them to delete it for me.
