Been checking out how it acts with all of my v8 saves. I have 4. 2 work, one claimed I was cheating and one sent me to main menu. Here's the thing- all the saves started from the same save starting with v7. I wonder if it's messing the stats with the anti-cheat deal and it's what's causing issues with the saves?
What I have started to do is follow one girl per day and if the number of scenes doesn't move up, I switch to another one and if that didn't work, switch to the third and it usually brings me some progress and just enough to make it up. I've only seen hints if you go to the master bedroom at night. IIRC, it's 2200-2300 or so. And it's like one line and you can miss it.
