No beehives?

Hello! today,while trying to find bees in the plains biome,I could not find any even in newly generated chunka in my world generated from beta 1.16.066,and even tried a test world to see if I could find any beehive,and even tried bonemealing trees,but nothing works.However,older worlds seem to be working fine

how to repro: 

1.load up a fresh world.

2.find a plain/sunflower plains

or,

1.find a sunflower plain

2. grow trees

 = you will find at least one beehive

 = none are found 

or am I having extremely bad luck?
