In ne wsnapshot, bees get stuck when too high above the ground. Also navigational system for bees makes them not go around walls.

Bees suddenly stop as if they are lagging for eternity when they get too high in the air. how to trigger:

1. spawn bees.
2.  wait until one gets stuck
3. (How I solve) climb up and nudge the bee.

ALSO

Bee's navigational system causes them to flying into walls instead of going around.
