I would like to chime in on this as this seems to be similar to a bug I have constantly, but it might be something else.
During my gameplay, I will occasionally find scenes that will just not play at all. Sometimes they're sex scenes, but they can be events too. I've never had it happen to a fight or happen to any scene that prompts choices mid-scene. They appear to be random, and save specific, but not related to the saveword. In other words, the event will never play no matter what I do, but I can start a new file and load the saveword and I can play them just fine. There always seems to be something missing from each game, but sometimes it takes me longer than others to find it. I've also never immediately encountered this bug, so I'm not sure if it's related to progress or time or anything.
I've noticed this happening over the last 4 builds.
