After some update I started to get these items holmium-solution-quality-based-productivity inside the machine after each craft.
They can't be taken out with inserters or loaders. The only way is manually.

Maybe it's related to the Factorio setting for showing hidden items?

I "fixed" it by changing the line

quality_holmium_solution_recipe.results = {
{type = "item", name="holmium-solution-quality-based-productivity", amount = 0},
{type = "fluid", name="holmium-solution", amount = 100},
}

Amount to 0. But I understand that this item is how you calculate the extra output...
Is my intuition correct?

Thanks

I've been having the same issue, in my case it only seems to affect the chemical plants placed on a space platform (to make use of Maraxis' hydro plant recipe and extra module slots)

yeah i have yet to update the mod, the devs changed the behavior of one of the entity flags but i haven't got around to porting it yet.

me too

Fixed in 1.2.0.

Error in assignID: technology with name 'legendary-quality' does not exist. It was removed by quality_unlocked.

yes sorry. i modified that mod so that it would work with other mods instead of crashing. checking... the save loads with it disabled. i have not modified any other mods in ways that would break anything.

also thx 4 hosting version control, i am playing happily right now with 1.1.3 (modified as above to effectively disable it) which i fetch from your version control

Stable is .47 whilst i'm using a feature from .48, to "fix it" for now change defines.inventory.crafter_modules to defines.inventory.assembling_machine_modules, there is no side effect to making this change.

(well not the modules, but crafter input & output, see this doc link for the opposite: https://lua-api.factorio.com/latest/defines.html#defines.inventory)

I'm getting the very same issue, using the machine with quality causes it to keep stopping after every other craft with an item I have to remove manually. Very frustrating, first time using the mod.

you are not supposed to remove the item, it is supposed to go to the hidden surface and get converted into said free fluids, head into editor mode and look around on the hidden surface to see what is going wrong.

I've already removed the mod and carried on, it wouldn't have been possible to proceed with my game if I'd had to keep babysitting the machine every few seconds.

well then lets hope that the next person includes a save file since mod compatibility issues like there are hard to diagnose without.

The mods I'm using (other than this one) are the additional quality tiers mod, the one to unlock quality from the start, and the shattered planet mod.
