Thanks for recommendation, i thought about something similar for gathering to get special ability dice, that would allow player to for example reroll any dice value, or set to any chosen value once a day, but that would require a lot more than 48 hours.
Also you are supposed to gain more resouces for being closer to 0, and for actually getting 0 you also should get gold, but i checked now and i messed up logic, so thank you!
