The recipes to make certain items uncommon-legendary directly from quality ingredients are disabled for quite a few items, even though they exist, such as steel and electric furnaces, all types of assemblers, modules, solar panels, accumulators, nuclear reactors, higher tier belts, red and blue circuits, all sciences except red science, and many, many more.

Have you added it to an existing game or did you run through the game as intended? The mod does some stuff behind the scene when tech is unlocked.

As a test, run this command (quite slow command):

/c game.player.force.reset_technology_effects()

Let me know the results. If it fixes the issue, I'll see what I can do about migrations.

Oh, this was when making a new test save with Editor Extensions. It's very possible running that command fixes it, i'll let you know if it changes anything

It seems to be an intricacy between Editor Extensions and how I do tech. It works fine in the normal game.

Will be fixed for next version
