While testing the new Bee functionality, two of the Bees around my Hives/Nests were found frozen in the sky (around Y 80). I punched one of them 5 times and it "came back to life" and went down to a nearby Hive. I punched the other bee and it died without regaining its AI.

Video shows the frozen bees and some active bees down near the ground:

I am so far unable to reproduce but will continue to test and report back.
