Fatigue and queen cages

" Earlier this year  I went to check if a caged queen installed into a nuc  made from a weaker  hive had released....”hmmm” I said as I lifted the inner cover.....where is the queen cage? Turns out I installed the queen into the wrong nuc, but in to one of course that had a queen". The newly released queen was nowhere to be found. This is what happens when I'm rushed, hot, and fatigued.
