And the whole MHY thing makes the story illogical and even causes the game to crash. Some NTR scenes crash the game too.
Game is working as intended - played like Ocean has released it. Don't had the time to play the full release, but the beta, and there was the crash in the one and only somewhat NTR scene because of a typo in the patch.
Messing with the game files through a third party mod or a third party patch is a sure way to kill your game. Thats a YOU problem, not the one of the dev.
It's the same if you play Stellaris that is modded to hell and back into oblivion, and complain in the official supportforums that a quest chain don't trigger ...
Without patch was all working fine.
What is illogical with the variable Miru horny (Mhy) ?
The game states clear that Miru has a high libido and William can keep up with it but finds it exhausting.
Stick a finger in Mirus pussy, turn her on and "blueballing" her will lead to consequences - if NTR is turned on and William suggest the open relationship and/or working in porn.
