Hi! Currently there is no support for modded recpies for landfill alt craft versions, so maybe you can add it?
I find this ones:
Cultered Soils from gleba_cultured_soil
landfill from soil from Dea Dia System
landfill from Externed Vanilla: refining
Landfill from crushed stone from Muluna

Not sure if they will be added but I will check them out. Thx!

i asked 2 other mod creators about adding alt ver of crafting concrete (https://mods.factorio.com/mod/concrete-productivity-modified & https://mods.factorio.com/mod/Paracelsin) and they both implemented it, maybe you can ask/see how they added it, so it will be easier for you

Issue is not with ability to do it
I just don't like the way muluna itself changes core parts of vanilla game, So I don't want to rly support it
It changes fluid flow ratio for everything in game to be 10-20x higher, and that breaks a lot of stuff in game like oil rig mining speed, pumps controlled by circuit and almost anything that uses fluid can have unexpected behaviour.
From time to time people come to me with issues related to this things, and I have no ability to fix it because it was not caused by ma code, and I don't want to touch it (muluna) more than I have to,
I did not straight up marked it as Incompatible because there is nothing currently present in code that crashes both mods when you try to run them

As for other mods. I checked gleba_cultured_soil and just added support for it.
I know author of Dea Dia and he plans to change a lot in mod (Rework it) so I will ask first if this recipe will stay for longer.
Did not checked on Extended Vanilla Yet, but will try to do it in this week

Cool, well, than ill w8 for externed vanilla

Hello there!

There's also Krastorio 2's recipe "Landfill with sand" not profiting from prod bonus. I just sent my robots to fill a lake without checking the recipe. Rip me I guess xD
