Hi. I've seen a bug that makes the bee's AI get frozen when they reach the coordinate Y<=0.
What I expected to happen was...:
The bee keeping flying without caring about the altitude
What actually happened was...:
When a bee reaches Y=0 or below, its AI freezes.
Steps to Reproduce:
1. Spawn a bee in an empty/void world.
2. Wait until the bee reaches Y=0 or deeper.
3. The bee doesn't move anymore.
