I currently own a Caterpillar and also have bought the upgrade to a Banu mechaman but i have not applied it because i don't want to spend the next year in a Starfarer. My question is is my upgrade token safe or can it be refunded or something like that if i dont apply it to the Caterpillar? also what happens if the Banu comes up in price does my game package become more valuable to exchange to something more expensive for free? Thanks
