i have finished and deleted the game already (tried NTR with matt again with no success) but i think 20 affection was probably the max value for mia anyway. corruption went up much higher than that though. affection for mom stopped at 41. hint: take your time before buying the booze for max' party as going to the party finishes the game soon after and you may miss out on a few events with mia especially.I ended up in almost the same scenario. I had to go back and get rid of Matt, but I am still stuck on 20 Mia Affection. Anyone know what the trigger for 21 is? And yes I know how to console cheat, but I don't even see what gets beyond 20 Affection in the Walkthrough.
