It's a tricky time around the bees - they have many concerns with sealing off drafts, they go in and out of a sluggish state as they near dormansy (you'll see this the most in the inner cover as bees make their way to the top on days when the sun warms the outer cover and then it cools off) that is when many bees get trapped above the inner cover in a dormant state.
They can be tempermental as Winter approaches, they can't afford any changes in their Pre-Winter settings and they just don't always understand that you mean well.
When dealing with sluggish bees who all of a sudden SNAP BACK into an alert mode, they can get nasty - sort of drunk or under anesthesia. I would imagine all will be well come Spring time when they aren't so concerned about the cold days ahead. I got my fingers crossed
I'm watching C1 and C2 closely. It's been overcast for days and VERY FEW flights have been made - I popped off the outer and inner covers and they too weren't all that happy with the Beemaster (obviously they haven't seen the website - lol) so I quickly re-lidded them after seeing they were very busy doing tidying up jobs about the frames.
When all else fails, remember that as long as they can be busy doing anything (other than clustering) they will. Clustering is the "Get into the car and drive around slowly until next Spring" to the bees, everything else to them until then is just packing for the trip!
