The bug

Bees disappear in the nether after flying into a bee nest or bee hive to produce honey.

Expected behavior

The bees collect as normal pollen to gain honey from this and then fly again to collect pollen again.

Actual behavior

The bees collect pollen, fly back to their Bee hive / Bee nest and then disappear without producing any honey (the honey_level stays at 0).

How to reproduce

1. Go to the nether
2. Create a small flower meadow
3. Place bee hive / bee nest nearby
4. (optionally build a glass box around it so that the bees do not get lost)
5. Place bees with a spawn egg
6. Wait until the bees have collected pollen and return to their nest, etc.
7. After the bee has entered the nest, it does not reappear and the honey level has not increased
