[2.1.8] Hidden miner prototypes show up in "mined by" tooltip... Again?

[RandomUsername]

I've reported this in the past (viewtopic.php?t=125126), and it was promptly fixed, no idea how 2.1 reintroduced it.

For ease of reading I'll make the same report again:
I've made a mod that adds quality effects to mining drills, and done so by adding new prototypes, (and changing the placed item to the added prototype at runtime)

The added prototypes have the field "hidden = true"

They still show up in the mined by tooltip as so:

For reference the relevant prototypes being added do have the field "hidden = true":

Relevant code

Code: Select all

local qualities = table.deepcopy(data.raw["quality"])

local new_machines = {}

for mname, machine_orig in pairs(data.raw["mining-drill"]) do
    for qname, qvalue in pairs(qualities) do
        if machine_orig.mining_speed ~= nil and qvalue.level > 0 then
            local machine = table.deepcopy(machine_orig)
            machine.placeable_by = {item=machine.name, count=1, quality=qvalue}
            machine.localised_name = {"entity-name." .. mname}
            machine.localised_description = {"entity-description." .. mname}
            machine.hidden = true
            machine.name = "QualityMiners-" .. qname .. "-" .. machine.name
            
            machine.mining_speed = machine.mining_speed + (machine.mining_speed * qvalue.level * settings.startup["mining-speed-bonus-per-quality-level"].value)
            
            if settings.startup["drop-stacks-on-belt"].value then

                if not data.raw.tile["empty-space"] then
                    local empty_space = table.deepcopy(data.raw.tile["out-of-map"])
                    empty_space.name = "empty-space"
                    data:extend{empty_space}
                end

                machine.drops_full_belt_stacks = true
            end

            table.insert(new_machines, machine)
        end
    end
end

data.extend(new_machines)

Thanks for the report. It looked like with the Factoriopedia hide-unresearched things this got broken. It's now fixed for the next release (again).
