Since the thread has been closed, I'm putting this here instead: You reported a bug with structural integrity, regarding sinking the blueprint into the ground below the water. Your problem is that you were trying to place a CV , which can't be sunk into the ground. You can only place a BA sunk into the ground, CVs cannot be sunk into the ground. Hope this helps.
I don't know where you got that I was sinking a CV. It is a BA platform. Were you drinking alcohol when you wrote this?
