Proportion failure - Large drill

[EitanTal]

The large drill scaling ratio breaks down at some point, creating the drill appear about 15 times larger in each direction.

To reproduce:
Phase 1: Launch "Base Kethane Drill II p"
Phase 2: Click Back to Space Center
Phase 3: Goto tracking center, Re-select the same vessel, click fly.
Phase 4: ???
Phase 5: PROFIT! vessel is now ginormous!

Couldn't attach the file, as they only accept pictures. Please instruct me on which way is convenient that I shall send the file.

After poking the problem a bit further (hitting it with a stick), It turns out the problem has much to do with the drill being the first piece. (root node)

It even happens in this trivial craft here:

I have just learned there's a bug in KSP where root parts are improperly initialized. If that's not the case here, I'll need your output_log.txt file.
