KubeJS error:

[13:18:47] [ERR ] startup_scripts:bees.js:70: Failed to create recipe for type 'minecraft:crafting_shaped': 1x resourcefulbees:mutant_bee_spawn_egg is not a valid result!

All other bee eggs work except for the Mutant I created and I can't figure out why. Recipes for other bees require Mutant, and information shows Mutant as a required breeding parent. But no matter what I do, and I've been working on trying to trouble shoot this for three days, I can't seem to get it to recognize the egg recipe and it doesn't show in JEI when all the others do. I am stumped. Any help would be greatly appreciated. The Mutant bee does not show in JEI as an icon either. Thanks in advance.

That was it. Bee showing and recipe working. Now just have to regen the language file and that should fix that issue. Thanks.

perfect! let us know if you have any other issues :)

One final comment. Love the mod by the way. Nice change to generate resources. Kudos to the devs.

All bee file JSON are in the same folder as well. Forgot to mention that.

send latest.log

you're missing a # in front of your color

Figured, it was a punctuation issue. Thanks. Will fix that (many thanks for catching what I missed), and will report back. Your reply and help is GREATLY appreciated. Was pulling out my hair after three days of trying to figure it out.

you should have crashed for not having the # however bc of a change that was made the exceptions weren't properly being caught. our latest version (alpha) on curse has that corrected so it will crash with more useful information
