Alright. I ran into a minor bug in what I believe is Ch5. Robin seems to undergo a transformation of sorts? I was able to see this for the first time in a 'Hug' scene in the castle, yet... I had never had the conversation with Robin about this new look. I was then further confronted with this new form when trying to do something with Wendis when trying to make her body In the tower, where you first meet her. But again, I had not had any inkling as to why Robin suddenly had grey hair. I surmised it was something I had missed, or not researched properly but figured I'd bring it up. Amazing game, by the way.
Another bug I came across.. This one made me restart my 95 hour play through since my save was locked and I was stuck. There are 3 optional bosses at one point. Orgasmic Empire is one of them, the other two or somewhere else I can't quite recall. Tanurak spawns them. Well the OE one, you can't use Simon for, but if you save during the character selection screen, to save time, it creates a loop and gets you stuck, since the Auto-save feature also saves at that point. A minor detail, but given that my previous save was 7 hours prior... It was a bit of a irking thing.
