OK- Scorewatch tells me I have an update.  FICO dropped 30 pts. UGH! Now what?

Although CreditKArma reflected the mortgage inquiry, Scorewatch did not show a new inquiry.  Not sure what could cause THAT BIG of a FICO drop.  My CC balances jump around a bit, but not enough to cause 30 points. Is it possible that it is a scorewatch glitch that could correct itself? 

733 was good for the rates and terms I need on this refi, but 703 is probably not. Now I am scared.  I thought the appraisal was going to be the only possible problem, but now this!

What will happen? Will they use the original FICO, or am I screwed?
