Describe the bug
Using the Min/Max Y level to target a bee underground does not seem to be causing bees to spawn. To be honest, it doesn't seem like any bees are spawning underground. I tested this by loading an instance with just Resourceful Bees and World Stripper - stripping many chunks while looking for bees to spawn. I was flying around in peaceful, so the bees aren't being competed out by hostile mobs.

To Reproduce
Steps to reproduce the behavior:

1. Install an instance with just Resourceful Bees and World Stripper
2. Use the bee JSON supplied below
3. Search for bees underground

Expected behavior
I'm hoping to be able to target some bees underground, and require players to go caveing to find them.

Screenshots or Crash Logs
None - Bee JSON at the bottom.

Dawn and I tested this a while back and we’re able to confirm that bees do spawn underground they are just exceedingly rare. Not sure if I should leave this open or close.

I don't want to discount the idea that I've made a mistake here - would be happy enough to hear "it works over in this pack with these settings". Only reason I think it might not be me is the world stripper + only RB testing I did.

I’m not sure that much testing has been done on the y-level restricted spawning tbh. It was kind of a “hey we can check this value here, let’s do it” thing. I just happened to be looking at the method for something else and figured I’d take a peek quick but wasn’t able to find anything that was different between our bees and a zombie.

Just wanted to put some info on this issue. I didn’t look into it specifically yet but I did happen to look at entity spawn placements and did a quick comparison with the zombie. We use the same height map and spawn rules so I’m not entirely sure what’s keeping them from spawning underground. I need to look a little bit deeper in the hostile mob classes to find out.
