After updating to 1.17 the bees in my safe, enclosed honey production facility were ALL gone. When asked, no other players in the realm reported any incidents or possible explanations. Nearby bees in other outdoor hives were still there, however.

I've been working on repopulating those hives over the past few days but as of today the bees have all mysteriously vanished once more. This time, bees in other hives nearby are also gone.

Bee populations sure have it rough with that tendency to leave their hives and fly northwest and now this! I strongly suspect some bug is to blame because the building which contained the missing bees was always safe for them in the past (and had in fact proven to be the only way to maintain a stable bee population for honey production).
