I have a really annoying problem with the pie chart. At first, everything is normal, I can control it with my keys, but when I want to go back to the submenus by pressing 0, nothing happens. The pie chart works correctly with the 1-9 numbers, but I cannot go back. I have to restart the game to get to the main menu again. I really want to see this issue fixed, so I can finally use my pie chart.
