How exactly do I add mods to the ignored list in the no_quality.lua file? (Or another file which would be required)

I am not an expert in lua but I tried adding the corresponding subgroups of the items which didnt work all the way.
At the launch it just tells me (For example when excluding waterfill) "Error in assignID: tile with name 'water-quality-2' does not exist."

I love this mod and if I would be better at lua I would really think about asking you to collaborate ^^

Before requiring the no_quality feature, this might be a bug that should/could be fixed generically.
Also please add the full error message. It should show which prototype this error came from.

If you want to add compatibility with your mod, then do the following:
Add janky-quality as a dependency in your mod.
jq_entity_mods is a global. In the data stage, add your prototype names to jq_entity_mods.no_quality i.e. jq_entity_mods.no_quality["my-proto"] = true

Will be fixed for next version
