What if assemblers only assembled? This is an overhaul mod that introduces interesting production chains and design choices. New ores, new concepts, new assemblers, new intermediates -- and new challenges to overcome.
I would suggest changing the internal name of "iron-plate-stock" to "iron-plate". it improves mod compatibility and you don't need to call the remote interface for the crash site
edit: same with "copper-plate-stock" and "steel-plate-stock"
Wouldn't it be more reliable to super-seed plates with ingot/bar/billet/slab (or the German "Bramme" just to confuse everybody).
Then replace the icons and the vanilla recipe in final?
Plates are already highly refined, doesn't match really with the theme you are going for.
But technically only a hammer is needed. (and time, a lot of time lol)
Also I think it's the mods fault, the difficulty recipe selection looks like it could overwrite stuff without respecting other mods.
Still having this issue, Can't craft normal ammo, possible incompability with mod "Tracer ammo", since I deactive that mod it return to normal.
I reported the error on their end. They replace the regular recipe with itself for whatever reason. I told them that if they need to modify the regular recipe, they should do it by modifying the regular recipe, not by copying it and making changes.
