Im looking into it. They aren't getting the growth bonus from Promethion correctly, so that definitely needs fixed.
I think this is missing the point. If you would tie the presentation of the mechanics to the calculation of the mechanics, I wouldn't be complaining. As a player, it is more important to know what the mechanic is than whether it is balanced or not. If I knew that buying promethion wouldn't affect my growth, I wouldn't waste my credits trying. But instead you refuse to present information on the mechanics to the player and make us constantly play these guessing games.
When I watched Explorminate's video this week, I was more appalled that he was completely in the dark about how Onyx Hive worked than I was that the "battle viewer" was completely busted. Since he is a very experienced 4X game player, I expected him to pick up on things I missed and play Onyx better than I did. The fact that he can't figure this game out either should tell you how far away you are from having a real game.
