    # Before we start anything. I would like to refresh the cash of the assets.
    # so I would have the most up to date list / fractions of each item.
    
    # In the studio/story.py there is the get_asset_data() functions. Which if
    # you look closly just loads fraction into a dictionary called win.assets
    # from which we can read directly. 
    
    # The function is designed to give load the fraction ones and then just give
    # you one from the RAM. So it's not always going to read the asset.progress
    # files which is not too good. Since I want to have a good idea about the 
    # asset's actuall fraction. 
    
    # One way I can force it to update is by using the force argument. But doing
    # it on every frame defeats the purpose of the function entirelly. So here
    # what I'm going to do. Each time I close this window. AKA return anything
    # I am also going to wipe the dictionary win.asset clean. It will take one
    # frame of potential lag to load everything back ( at least the stuff that's
    # ont the screen in a given moment. 
    
    # Also to make sure that this dialog has the up to date info. I will do it
    # as well in the studio_dialogs.py when initilizing this function. So yeah.
    
    # Let's continue with the program.
