I'm not sure why, but in freeplay with everything already researched/unlocked (from when I created the game) there are certain things that I think didn't get marked as researched/unlocked because I can't build them. For example the bigger solar panel. There was one other thing too but now I can't remember, sorry. When I try to place it down it just shows red even though there is nothing around and I have more then enough materials to make one. I've tried using the abandoned tablets but so far each one I've found has just said all tech has been researched or unlocked. I can't remember what it says exactly. Thanks for looking into this.
