I can't get a lot of items out of scrap. The only things I'm seeing are iron & copper plates, ammo magazines, gear wheels, stone furnaces, stone bricks, yellow belts, yellow inserters, plus electronic circuits and red science once unlocked, and that's it. No labs, no boilers, no armor, no steam engines, no burner inserters, no chests, no power poles, and as a result I eventually run out of items entirely.
My Factorio updated today. Maybe related?
The only mods I have loaded are base 2.0.72, elevated rails 2.0.72, quality 2.0.72, saplib 0.0.3 and recursive-recylcing 0.0.5.
