I checked w FGSR about this when I found out a few weeks ago and they confirmed the same for grad programs. I don't think it should affect your application since all documents were due in December so that is the GPA they are basing your admission on - and many applicants wouldnt have had their fall semester GPA associated w that paperwork anyways! And I could be wrong about this, but I don't think programs typically take post application information to determine who gets off the waitlist (but maybe someone can advise me otherwise!). I'm not sure if that helps you at all, but hopefully it relieves some anxiety about your GPA and application status
