Can't unlock Medium Solar Panels even though i've unlocked both required research items. I've done both the blueprint as well as the silicon purification, and researched the antenna, but the Medium Solar Panel still remains grayed out and i'm unable to unlock it. I sware i unlocked it in a previous save and then i died and had to revert back and i've been unable to unlock it ever since. I've started a new game now as well with the same issue.
