bees not harvesting hives or nest in 19w42a

In 19w34a, someone else made this and it got fixed. Now in 19w42a, once again, bees aren't actually harvesting the honey. They pollen the flower, and go in the bee hive/nest, yet not exiting. I afked for 3hrs and they never produced any honey levels (I checked the level in debug info [F3]).
