Any idea on how I can create a mod for this?

[IsakMDMA]

I changed the values in the StoryMode.dll but since they update the game on a daily basis I would like to do it externally instead of changing the value every day. The code basically checks if the player has played the campaign for more than 10 years and if he has it fails the main storyline quests.

I changed both values to 50 and it works but its just a temporary solution
