3. Spawn 3 bees
4. Wait for the bees to go inside the nest/hive
5. Once they are inside, wait for a few minutes

The bees never leave their nest/hive.

Expected Results:
Bees should be able to leave their nest/hive when a flower is in front of it.

Original Description:
Bees do not leave their hives or nests if it is not in direct sunlight. I experienced the bug when i updated to 1.16.100 and I noticed that my bee farm don't produce honey and beeswax. I checked the hives and there are no bees coming out. There are 68 beehives in my farm and none of those left their houses. Each hives contain 3 bees. Also, I did manage the bees to leave their hives by simply breaking the hive with a silktouch axe. Also, i noticed when there is a direct sunlight, the bees would actually leave their hives just like what it is intended to do. I breaked and placed all of the hives at nighttime and I expected at morning it to work. Unfortunately, after I slept, all of the bees maintain to be in their hives even at daytime. I need to stock-up some beeswax for the upcoming 1.17 update that brings candles into the game. I hope this gives you enough information and fix the bug as soon as possible. Anyway, stay safe guys! Happy Holidays!
