Like the title states, when the forge mod AlmostUnified is installed alongside Create: Diesel Generators and it's dependencies the diesel and gasoline fuel types will not burn in CDG engines. I'm going to add CDG to the priority list config for AU and see if that fixes the issue.

Can confirm: Adding CDG to the AU config does NOT fix the issue

doesnt seem like a CDG problem

CDG engines aren't burning fuels that are tagged as forge:diesel or forge:gasoline, which they should, or are CDG engines designed to burn a proprietary fuel?

CDG registers a few fuel types for these tags by default: forge:biodiesel, forge:diesel, forge:ethanol, forge:gasoline, forge:plantoil
they are defined in data/createdieselgenerators/diesel_engine_fuel_types
maybe they are prevented from being loaded?

I had a thought that maybe AU adds a fuel type and there is a typo, or something. There was a bug that caused all fuel types to be removed when one fuel type had a typo (fixed in 1.3), but I checked and AU doesnt define any fuel types.

Ohhhhhh. I think it might be an issue in conjunction with AU and Load my f***ing tags, then. I think it's an issue with them both, because LMFT prevents tags from breaking completely if a mod adds an invalid entry to said tag, and that in conjunction with AU might possibly be overriding CDG. I'll reinstall the modpack I had and get back to you if that's the issue.

Nevermind, it's just straight up an almost unified problem. However, after looking through the logs I realized it only changes 9 recipes so I don't even think I need it. Apologies if I wasted your time, though I appreciate you telling me how the mod works to help me figure out the issue.

No problem. You didn't waste my time.

I'm also sorry you had to wait so long for my response.
