Hey everybody. I want to add +1 chaos corruption on all settlements to Unholy Communion and Daemonic Pact research tree. My reasoning is that when the WOC event spawns the chaos starts to spread +1 to everywhere and then when the Everchosen arrives its +1 again for a total of 2 corruption but as the player we don't get that all. Can anybody help me out on where to start?

I at the moment trying out this tutorial https://steamcommunity.com/sharedfil.../?id=702343155 cant get it to work either.
