I see in the latest release that you've suggested this updates and will reload. Playing on minecraft 1,16,5 with forge 36.1.30, and cucumber library 1.16.4-4.1.10 and this is all that's generating in the cucumber-tags.json

}

I've even pulled out the file and placed it on my desktop to force regeneration of the file, but that doesn't seem to change it either.

Do you have mystical agriculture installed? It'll only generate entries that are needed by my other mods.

I don’t have mystical installed, but I believe I have one or more of your other mods installed. Full mod list at https://www.curseforge.com/minecraft/modpacks/trogarus-skyblock-bees-adventure

I am the pack dev and wanted to make sure this wasn’t an issue. Thanks for your mods and time to reply.

I think it's just MA that uses it currently, so I would say it's working as expected.
