So I'm using script.on_configuration_changed to unlock recipes that should be unlocked if the player is adding this mod to a game in progress. I use the following function:

Code: Select all

function retroactivate()
    global.MTBF_meddling = global.MTBF_meddling or {}
    --log("Performing migration.")
    game.print("Doing migration 1")
    for _, force in pairs(game.forces) do
        for __, tech in pairs(force.technologies) do
            if tech.researched then
                for ___, effect in pairs(tech.effects) do
                    if effect.type == "unlock-recipe" and string.find(effect.recipe, "broken-") then
                        game.print("Doing migration 2")
                        force.recipes[effect.recipe].enabled = true
                        force.recipes["robot-control-module"].enabled = true
                        force.recipes["robot-powercell"].enabled = true
                        force.recipes[string.gsub(effect.recipe, "broken%-", "disassemble-")].enabled = true
                    end
                end
            end
        end
    end
end

When I load the save, the matching print statements fire. But the expected recipes are not unlocked! If I copy/paste from the first for loop to the matching end and paste it as a command, the recipes unlock as expected.

The running mods list are as follows:

Thanks for the report however I don't see anything that's a bug here. The event happens after the game is loaded directly before the next tick happens; everything is loaded and ready to run.

Unless you can show there's some logic error in the game it just seems like you have another mod which is changing recipe enabled/disabled status maybe?

Nevermind. Turns out Bobs mods was calling force.reset_technology_effects() and this was undoing my script. I added an event to respond to the reset and it works now.
