Extension applications being processed out of order?

I see from the processing timelines thread and also from Trackitt that some applications where biometrics were done around 14 July are starting to be returned. Mine were done on the 2nd (or 3rd... something like that) and I've not had anything yet. Did they just skip 2 weeks?

I was well within the 15 days limit for biometrics, but I didn't do them immediately on receiving the letter.

Am I freaking out over nothing? I hate this wait. It's been nearly 5 months!

Thanks!
