Hi I am getting this error with the PlanetsLib Mod (https://mods.factorio.com/mod/PlanetsLib) for Factorio 2.1

Failed to load mods: PlanetsLib/lib/surface_conditions.lua:56: attempt to index local 'recipe_or_entity' (a nil value)

gleba_allow_on_arcanyx("recipe", "tree-seed")

good luck

So applying the fix uncovered another error...

Failed to load mods: Error while running setup for recipe prototype "s6x-arcanyx-recycler" (recipe): Recipe has 'crafting' category but has a non-item ingredient 'azoth' (fluid).

From my testing this is related to the crushing industry compat. I have not found a fix for this because I cant find anywhere a reference to this recipe xD
Disabling crushing industries allows this to load without erroring.

another temp solution to the error.

same location as the fix for the other error but add this to the if (mods["crushing-industry"]) then so it looks like this :)

Line 97
if (mods["crushing-industry"]) then
if data.raw.recipe["s6x-arcanyx-recycler"] then
data.raw.recipe["s6x-arcanyx-recycler"].categories = {"crafting-with-fluid"}
end
CrushingIndustry.concrete_recipes["s6x-arcanyx-recycler"] = {ignore=true}
end

Thanks for helping out with the temporary fixes. This should be fixed properly now.
