Oh, you'd be surprised at the things you can learn while you're doing alterations.
Mods introducing new content into the game.
Armors or armor equipment.
Nuclear armor doesn't have energy shields as a tech prereq. As a result, you can gain 'access' to it before you can gain access to energy shields, which might mean you actually can't make it for quite a while (AKA Space exploration)
Noted, thanks.
Fixed.
