This game has less features than other idle games, which is fine since it's obvious the game is still in development. But, I reached a very late stage of the second planet before the rank 60 update, so the mission to buy a new deposit became a problem, especially when deposit #37 is not only expensive it also is bugged and you can't buy it. So this game punishes the player for making it further in the game before update releases. Please either change your missions or the planetary condition.
