Please only change the concrete recipe. Currently it also chances back a lot of other recipes back to their original.
Remove all other recipes from recipes.lua:
data:extend({
{
type = "recipe",
name = "concrete",
energy_required = 10,
enabled = false,
category = "crafting-with-fluid",
ingredients =
{
{"stone-brick", 5},
{"iron-stick", 2},
{type="fluid", name="water", amount=100}
},
result= "concrete",
result_count = 10
}
})
