Therefore, in theory, removing any mod should now automatically run these scripts and fix this issues for you.
If that's not the case, let me know, but if you have the latest experimental, from what I understand the game SHOULD fix itself now.

Hence my suggestion that the mod tries just hiding the vanilla items rather than remove them. The mod is called Dectorio by the way. https://mods.factorio.com/?q=dectorio

PantherX wrote:The mod hasn't removed the item definitions since 0.5.9 as this was causing issues with other mods that relied on the item being present. It currently does disable the recipes to prevent the item being crafted and it switches out the sprites on any existing vanilla hazard tiles to use the modded ones to maintain backwards compatibility in case the mod is later removed.

The issue here is that when the mod is removed, the vanilla recipes that are disabled (in this case, the hazard concrete) are not being re-enabled.

	if DECT.CONFIG["disable_hazard_concrete"] then

		-- Remove base Hazard concrete (as it's replaced by painted concrete)
		data.raw["technology"]["concrete"].effects = {{
		        type = "unlock-recipe",
		        recipe = "concrete"
		    }}
		      
	end

local neweffects = {}
for _,effect in pairs(data.raw["technology"]["battery"].effects) do
	if effect.type ~= "unlock-recipe" or effect.recipe ~= "battery" then
		table.insert(neweffects,effect)
	end
end
data.raw["technology"]["battery"].effects = neweffects

PantherX wrote:Well it would be interesting if that is indeed what is causing the problem. Strangely, though I've noticed that if you remove the mod and then go to the technology screen the hazard concrete does show correctly as being a recipe that is unlocked by Concrete, so the technology tree itself is resetting correctly and the item is being prototyped, it just doesn't seem to enable the recipe for crafting.<snip>

Rather than disabling the hazard-concrete recipe in your mod, have you instead trying merely hiding it (and the associated hazard-concrete item)?
