I had to downgrade to 1.2.7 to get my Fulgora scrap recycling recipe back, in the latest version it was just voiding the scrap (Giving 0-1 scrap) and filling my belts with scrap itself instead of the items it turns into. Not sure why since you updated the mod to fix that, but seems it either got bugged again or something borked with your last updates.

I've tested it on newest mod version on factorio experimental and it works flawlessly.
Can you send your mod list so i can test what causes this bug. Thanks.

Here you go, quite the list

I had the same issue too.
Using it along with the "Warp Drive Machine" results in errors.

Found out conflicting mod: "augmentor" Because of the new scrap recipe you did it breaks that mod, which breaks this recipe.

Good job
I also have the "augmentor" mod installed.

Please mark this mod as incompatible, it runs perfectly fine without enabling K2.

Having the same problem without "augmentor".
Tested a couple of versions without success.

Look for mods that change or has some scrap related stuff to it, try disabling those and see if the mod works or not. That's how it so far breaks.

Found another conflicting MOD "Mining Drones", which causes the same error when enabled.
Did this mod also change the recipes?

Well, "Mining Drones" was it for me...
Didn’t know that changed anything with Scrap.

I didn't get holmium ore from scrap recycling. So i can't play

Can confirm that the Augmentor mod does break recycling. I just turned it off after reading here and that restored Recycling to working order. Hope this helps for anyone else looking into this issue.

The problems with recycling are caused by incorrect load order ,so adding k2so as dependency to one of these should fix the issues

I didn't get holmium ore from scrap recycling. So i can't play

For everyone who as me dont get a holmium ores, i playing with mod "Factory Levels", so i turned it off and everything is fine for me now. So Polka_37, mark Factory levels as not compatible with your mod, or try to fix it.

I have this problem with ver. 1.4.20

also have this problem, guess i have to replace the mining drones

After a day of fighting I have a solution, the problem appears when the Krastorio mod and mining drones are turned on together. It takes a while to get it working, but I haven't found another option.
1) In the Mining Drones mod, add the Krastorio space out in the dependency to the info.json.
this itself doesn't change anything so you have to modify 2 files in Krastorio space out
2)in the recycling.lua file, delete everything but do not delete the file itself
3)in the data-final-fixes.lua delete

-- Generating the recycle (reverse) recipes
for name, recipe in pairs(data.raw.recipe) do
recycling.generate_recycling_recipe(recipe)
end

local generate_self_recycling_recipe = function(item)
if item.auto_recycle == false then return end
if item.parameter then return end

if not data.raw.recipe[item.name .. "-recycling"] then
if not string.find(item.name, "-barrel") then
recycling.generate_self_recycling_recipe(item)
end
end
end

for type_name in pairs(defines.prototypes.item) do
if data.raw[type_name] then
for k, item in pairs(data.raw[type_name]) do
generate_self_recycling_recipe(item)
end
end
end

data.raw.quality.normal.hidden = false

After these actions, everything works as it should for me

Thank you sir! Saved me from hours and hours of googling :-)

I have the same problem with the 248k Redux Mod. How do I fix it?
