Getting the following issues after updating Space Exploration and a few other mods today:

adjustable-quality/data-final-fixes.lua:2: attempt to index field '?' (a nil value)
stack traceback:
 adjustable-quality/data-final-fixes.lua:2: in function 'setting'
 adjustable-quality/data-final-fixes.lua:133: in main chunk

Mods to be disabled:
▪ adjustable-quality (2.0.57)

Do note that I am using the quality fork mentioned below, neither that mod or this one has updated though, any ideas what could be causing it?

I see, the options for that mod are dependant on "space-age" being loaded. They seem to have added something to data.raw["chain-active-trigger"] to cause the if statement to return true. But the setting does not exist because space-age is not a loaded mod.

this is the related section having the error:
if data.raw["chain-active-trigger"] then
for _, obj in pairs(data.raw["chain-active-trigger"]) do
obj.fork_chance_increase_per_quality_level = setting("fork_chance_increase_per_quality_level_chain_active_trigger")
end
end

and

if mods["space-age"] then
data:extend({{
type = "double-setting",
name = "fork_chance_increase_per_quality_level_chain_active_trigger",
setting_type = "startup",
default_value = 0.1,
minimum_value = 0,
maximum_value = 1,
order = "m0"
}, {
....

this will require some rethinking how this setting is added. Either that or changing the if statement to only adjust this when space-age is loaded.

you can help me fix this by providing the addon name for space exploration from its json file.

"name": "space-exploration"

That one?

I thought about this some more, and it will require the name of the alternative quality addon as well.
I am not sure which settings will be available for that combination (other than the fork chance)

"name": "quality-se"

https://mods.factorio.com/mod/quality-se

ok, new release should allow the setting for fork chance to load in either situation. (space age or S-E and alt quality)

let me know if there are further adjustments required.

Seems to work so far, thank you so much for the fix, its extremely appreciated. Will let you know how things go
