Hey Cory, it is indeed still an issue in 19w42a, would be glad to share the test world, was hoping to make a video on the setup though so hopefully no one steals credit c:
[media]EXTREMELY IMPORTANT NOTE:
Every time i close and re open the world, all the bees regain functionality for a moment, but again, after an hour or so, half have returned to doing nothing, and after a couple more hours, not a single bee is functioning.
P.S. : this is happening every time i try to recreate it.
More video detail: https://youtu.be/hK4ikHU-CDM
At this point the AI of every bee in all 20 cells I'm testing have failed, not a single one is pollinating nor even moving at all anymore.
It seems the problem is in that if they can't access the block location via an obstruction when they mean to, they cease trying, and remain still.
Another note to point out that this isn't a duplicate of MC-159447. Bees that hit a fence post while following a player holding a flower, triggers that bug to occur, however, showing a flower to one of the "dead" bees I'm reporting, causes them to path towards the flower (me as the player) with no issue, but when the flower is hidden again, the bee remains nonfunctional.
Done, glad to help! Thank you for working on this 😃
