On the hunt for flowers, some bees may wander too far and/or simply never return to their home hive. Inversely, they can pop out of their hives and wander away forever, ignoring flowers.
They can also just collectively decide to become flying potatoes and drop what they're doing to go fly aimlessly in any direction.
It seems they get stuck in a sort of wandering mode until the world is reopened, where they can then path to the appropriate goal. If they're not already near a poi, they may easily glitch again.
How to reproduce:
1) Start a new world and examine bees as they go between flowers and their respective nests in either a natural or artificial setup.
2) I don't quite know the conditions under which they forget what to do, but it happens often. When one doesn't come back, manually lure or lead it back to the nest yourself. It may have completely forgotten or become stuck in a wandering mode and will usually not re-enter.
If you exit the world and rejoin whilst the bee(s) is near the nest, it will immediately set a path for the nest it could not see previously.
