Good, as long as it's not just me, I was beggingn to doubt myself. I have had 4 mated marked laying queens just disapear into thin air, left a handfull off bees behind. All in the same yard as well.
My personal theory is that bees will change their minds at the start of a strong honey flow and an oncoming spell of good weather especially if the weather has been cold and wet beforehand. I have seen abandoned and torn down supercedure queen cells as a result. Disappearing bees - yes odd one that. I'm seeing more in recent years. More than I ever did years ago.
