デベロッパの回答 、 Thank you for reporting this issue, it will be fixed in the next update. At this point, energy should go back to recovery after the player spawns at least one item from a generator. In case you have 0 energy, we reccomend taking energy from Gift Ladder, Lucky or Energy ad and then using a spawner. In case the problem still persists, please contact us support@boompickgames.com and provide as much info as you can, including device and operating system.
