I noticed that Processed Fuel is not stackable.
I added it for myself to the mod, but I was wondering if it is intended that way for balancing reasons or if it is just missing from the mod?

I can add it, but there's no baked icon for it. Using auto generated icons is bad for UPS, afaik.

I did not know that. I thought it only cost performance on startup or at least that it is a one time thing.

Composite icons draw the entire icon below the icon over it. So each 3 piece composite icon has the computational cost of 3 normal icons.
not including the blank layer. then again, stacked fuel is not an item that should exist in that many places.

Mernom, inside the graphics of AAI's base mod, there exists a stacked processed fuel png. could you please add it? I'm still gonna mod it in myself, like Kyth has, but the png file is baked by definition, right?

Did I not upload a fix that enables it?
I'll check it out tomorrow.

It's a bit bugged though, I think it doesn't count as fuel.

Ah, I'm on the older 0.2.18 version. That must be why.
