To be honest ... I've never really paid any attention to the value of space rocks before analysing them.
I've just analysed them, and received the various messages, cheering silently when they are stated to be more valuable than their initial assessment and booing silently when they are stated to be valued considerably less than their initial assessment.
I have never managed to get the alternate futures in the ITF world, however ... instead loving the Star Trek inspired clothing, build objects and buy objects it brings into the game.
In your game, are you having the same issues with space rocks from your base world? And is your base world Island Paradise? Could it be some kind of interplay between ITF and Island Paradise packs?
