First of all, thank you for creating such an excellent game.
Whenever I have multiple rockets ready, clicking to upgrade the space station—even if only 120 materials are required (and a single rocket’s payload would be sufficient)—causes all rockets to launch at once. This results in serious waste and storage overflow at the station. Is this a bug, or an intended game feature?
As shown in the figure, many of my rockets were ready to launch. However, when I selected the upgrade, almost all of them launched at once, each carrying 240 upgrade materials, while only 120 were actually required. This caused a severe overflow of materials in space (with 10,947 already stored in the station).
Once again, thank you for your hard work and dedication to improving the game
