If a mod adds a recipe that is unlocked by a research, and that research is already researched when you add the mod, the recipe won't be unlocked.

Suggested fix: whenever you load a new mod in an existing save, go through all researched tech and re-unlock all recipes.

If that is already possible in the mod itself, please let me know.

Yes, that is already possible, the migrations are used for that: https://forums.factorio.com/wiki/inde ... on_scripts
