Ok, 26h of game and i'm guessing that "unlocking" futher corruption isn't in game yet.
I probably miss things (and that's a shame :( ) but i finally reach the city with nearly all affection/trust unlock.
I will still trying to complete both first corruptions in the future ! Gj for the quality of the game. o/
PS: You will probably see me when the next update will be released :D
