What should i change in the coal_generators_fuels.json?
I've tried adding "#minecraft:blaze_rod", to the file, but the coal generator brokes and it doesn't work with anything.
Also, I've tried to delete the coal_generators_fuels.json file and it doesn't work either :c

You want to use minecraft:blaze_rod or #forge:rods/blaze. A leading # means tag, otherwise it's an item.

It works, you are awesome.
Thank you!!!! ♥♥
