The Bug

Bees do not leave their hives in the Nether and the End when first placed. Bees also do not leave their hives if the weather changes from rain to clear while in the Nether/End. The world must be reloaded to make them leave their hives.

See the reproduction steps below for more details.

Steps to Reproduce (First Placed)

1. Set the time to night and the weather to clear.
2. Place a bee nest and summon three bees next to it so that they enter the hive. Break the bee nest and collect it.
3. Enter the Nether using:

   /execute in minecraft:the_nether run tp 0 128 0

4. Set the time to day and place the bee hive with bees.
5. Note how the bees do not exit the hive.
6. Reloading the world makes the bees exit their hive after some time.
