Structure placing does not perform validation check on actual placement

When placing a structure, a validation check for spacing is not performed upon performing the  build action which can allow you to stack structures together like this:

The main reason I report this is for mod compatibility purposes/futureproofing purposes. Some mods have unique structures that can be placed on water, but due to the scenario of a boat moving onto the position the player chose to build the structure and lack of validation, can have the structure inside of the boats physics box causing some wacky shenanigans.

This can be fixed on the mods end, but I figured it may be better for it to be officially patched in the case the vanilla game does something akin to this (Or some other weird bugs from being able to place structures within each other happens)
