Thanks for that awesome trainer. It makes the game pretty easy . Every option except "Numpad3 - Coal" works flawlessly.
Please verify that you use our latest trainer and the latest game on Steam, that you have at least 1 piece of coal in storage when using option Numpad 3: Add Coal and that you haven't any of the options Numpad / or Numpad * enabled.
Other than that, please provide a savegame of yours. You have to zip/rar/7z it before you upload it here.
