it's still an issue in 1.15.1 Nathan Adams & Michael Wobst
Should also add to the unprovoked, shulkers because as soon as you get near them they start attacking with invisibilty still present in 1.15.1
@Dmitry Konev I know that what I'm saying is when I'm in the nether and my chunks are optimized the bees fly out all at once but whenever I leave the nether or go off to the overworld and then come back they occasionally go in the bee hive/nest and then never come out until another optimization.
edit: it's kinda like as soon as the chunks are unloaded the timer on when the bees should get out of the hive and back in again messes up so they never leave the hive/nest
yeah lans are bugged out currently when trying to play on seperate computers me and my friend had to buy a realm to play together.
Still an issue with 1.17 RC-1
