Hello, I added this mod to an existing map, and have found the recipes are not showing in the crafting menu.
I already had concrete researched on this map.
I looked through the code and do not see a migration script, perhaps that is the issue?
You may need a migration script along the lines:
for _,force in pairs(game.forces) do
force.recipes["colored-concrete-1"].enabled = force.technologies["concrete"].researched
...
force.recipes["colored-concrete-n"].enabled = force.technologies["concrete"].researched
end
Thanks for the great mod.
