For whatever reason, the recipe for coke dust in version 2.7.1 has no ingredients, so I get effectively 6 MW of free power per crusher if I choose to burn coke dust in boilers. Methinks this needs fixing lmao

This seems really strange to me, can I say? xD
I'll give a watch - but are you sure it is not one of the mods you've installed that's doing this?

Unless "no empty barrel here"(https://mods.factorio.com/mod/noemptybarrelhere) or Bob's Functions Library mod are removing the coke from the recipe, I don't think so. They're the only mods listed as affecting the recipe, at least.

I just took a glance at your mod's recipe.lua and I see no reason why it wouldn't work, weird... I blame Bob's, I highly doubt the no empty barrel mod is to blame.

Are you playing with Bz mods maybe?

Nope, I have no mods that add new ores.

I tried with different setups and settings, and couldn't replicate your issue.
Could you please give me the list of the mods you're using and that made the bug appear?
(Finally found some time to mod, yes. :D)

As my modlist is massive, I'll just provide the save file: https://drive.google.com/file/d/1XaNDLczt-1rJo2TNJzBr9YCzCQuDDeEd/view?usp=drive_link

Give a watch if the problem still exists now that coal processing was revamped.
