Position looks correct, but their direction is wrong.
Sadly github won't let me upload a screenshot right now... will do that once github works again.

Yes pictures please. And a list of the steps to reliably reproduce the problem.

Steps to reproduce:

1. make a simple craft with ISDC
2. "Launch" it
3. Press quicksave and then quickload on the pad, don't even have to liftoff

Craft before quickload:

Craft after quickload (different camera angle, might just be the orientation of the SRBs that got messed with, their position looks roughly correct):

This is not just a visual bug, their thrust vector changed along with their visuals.

Interesting... I must have misused some of the transform operations in calculating of the orientation (and/or somehow the operation is being ran twice on vesssel re-load... which wouldn't surprise me given KSP's crappy loading sequence(s))

Issue #666, no good can come of this.
