When 2 Iron tanks are trying to form as a multiblock structure, they'll refuse to form when they are connected diagonally even tho the iron tank is "properly constructed" besides that.

I wanted to save some space placing both of them in a corner of a room, but due to them being connected diagonally, both of them refuses to form.

Its nothing major but i just figured i'd point it out incase someone else ran into the same problem

Size attempted with 5x5x6

You have failed to comply to the rules of structure creation, this is not a bug.
