manual save does work, at least for me. Always do everything you have to do, then save then close the tab. if you do anything after the manual save it will not be kept until the next autosave procs or manual save is used
energy seems to be too slow, by the time i can scan for a new planet i am able to upgrade it nearly to its maximum. this effect is making me not want to play for any consistent amount of time... especially compounded with my inability to see what scanning costs. I know the factor it goes by but I do not want to manually track that, I feel it would be a nice QoL update to display scan cost.
Scan cost is displayed when you mouse over the Scan button. I will update the game soon and hopefully fix the energy progress.
