Failed to load mods: Error in assignID: item with name 'angels-sintering-oven' does not exist. It was removed by TIMSABA.

Source: angels-sintering-oven (assembling-machine).

Only required mods are enabled. I disabled all other mods (optional planets, some QoL, etc.), reset mod settings and still get an error.

If you don't have time to wait, here's the solution:

1. Open the TIMSABA archive
2. Navigate to: TIMSABA /prototypes-final-fix/duplicate-items-and-fluids/
3. Open the angels file
4. Find the line: if settings.startup[setting_early_sintering_oven].value == false then
5. In the block: for _, BUILD in pairs(sintering_ovens) do, add the line data_assembling[BUILD] = nil before end

You'll end up with a code snippet like this:

    local sintering_ovens =
    {
        sintering_oven_1,
        sintering_oven_2,
        sintering_oven_3
    }
    for _, BUILD in pairs(sintering_ovens) do
        data_item[BUILD] = nil
        data_recipe[BUILD] = nil
        data_recipe[BUILD .. _recycling] = nil
        if mods [panglia_mods] then
            data_recipe[item_ .. BUILD .. _panglia_crushing] = nil
        end
        data_assembling[BUILD] = nil -- This line is needed for everything to work.
    end

Anyway, this issue will be fixed in the upcoming 1.4.0 update.

Corrected.
