Legendary substations were created in my inventory after blueprinting them in early game. Unsure how to recreate at this point, however after using them for spacing I've now (twice) had them pop up into my inventory after removing the blueprint. I am able to use them as if I researched the tech but I'm only at blue science,
I haven't tried different entities of items I shouldn't have access to, but I'll keep playing around to see if I can recreate the issue.
