Round tile 2x2 (14769.dat) is missing the connection on the center underside stud.
For that matter, I've noticed that snapping info is not generally included for any of the in-between underside studs/tubes on 2x or larger parts (not to mention the space between studs on the top surface). I'm sure this is intentional and I can fully understand the reason.
But I think it's worth including for the 2x2 round tile, since having that connection is fundamental to the (re-)design of the part.
