Decompile wManager.dll
change:
Vendor.BuyItem(wManagerSetting.CurrentSetting.FoodName, 1);
Vendor.BuyItem(wManagerSetting.CurrentSetting.DrinkName, 1);
Vendor.BuyItem(wManagerSetting.CurrentSetting.FoodName, 4);
Vendor.BuyItem(wManagerSetting.CurrentSetting.DrinkName, 4);
Recompile. Do this every wRobot update or wait for @Droidz to fix the loop that only goes for(var i=0; i < 10; i++), all he has to do is set it to 20 or 30.
