References issue #586.

There's still an issue. In FTB Evolution (productive bees 13.6.6) - instead of a crash, a generic configurable bee egg

is produced. When it hatches, an invisible entity is created

This entity can be captured in a bee cage, and it might even work like a vanilla bee, but I'm reluctant to risk it. Regardless, JEI tells me the egg does not work for recipes requiring an egg of a specific type (I was trying to create a ProsperiBee egg so I could make a supremium bee).

Potential resolutions:

• make a default bee (MineCraft vanilla?) that eggs with an invalid configuration default to
• add a tooltip/JEI entry for bee eggs saying that some mob duplicators aren't compatible
• use the no_swab tag (or whatever the mob grinding utils devs recommend) to blacklist your bees (https://github.com/vadis365/Mob-Grinding-Utils/blob/MC1.21/MobGrindingUtils/MobGrindingUtils/src/generated/resources/data/mob_grinding_utils/tags/entity_type/no_swab.json)
