What happened?

I recently reached LuV in GregTech and when attempting to utilize the Assembly Line no recipes registered.

I attempted duplicating the world and building a new machine in Creative Mode, but it did not work.

I created a new world and did nothing but make the Assembly Machine and insert components to make an Advanced Large Chemical Reactor, but that did not work.

The multiblock simply stays idle even when all items, fluids and research are added.

However, on a clean 1.20.1 Forge instance with only GTCEu Modern, PneumaticCraft Repressurized, Patchoulli and JEI installed, the Assembly Line works just fine.

I've attached screenshots of an Assembly Line and all attached block's GUIs in a new world with a random seed and cheats on.

In order? What do you mean? I thought the Assembly Line had freeform IO like other multiblocks.

make sure the recipe you are trying to craft has the items in order

sorry for the delay, the input ingredients need to be in the same order as shown in JEI
