Dave,
If it's any solace, I've experienced buzzing troubles with my Dragon's Wing (DW). Most of it was due to the fact that I like light gauge strings (.40-.100). This being said, it's the only bass I had to send back to the Mothership for a heat bend. If you're using standard gauge strings, truss rod adjustments should take care of the problem.
BTW, after the elves did the heat bend, my DW plays like buttah. None of my other Alembics have given me the least bit of trouble, and when necessary, I make adjustments which work out just fine.
Bottom line: make some adjustments, give it a couple of days, and hopefully that will fix it. It has for the most part in my experience.
Good Luck!
Alan
P.S. That is a beautiful bass.
