Ok the game does have 2 problems, though one is likely a rare bug.
1: Pictures (and most decisions) take too damn long to load. It just kills the pacing.
2: The bug I was talking about. My game suddenly slowed down and crashed not half a minute later. Now that on it's own is something I am used to. What I am not used to is it suddenly deleting my saves. I had at least one, maybe 2 saves way further in the game and woosh. Gone. Never seen that before. Most save slots are just empty. I still have 2 of them. One from and earlier playthrough weeks ago. Another from earlier today, but at the start of the game. The ones from the middle? Gone.
My guess is that it's a really rare bug, but man that sucks, especially because you can't speedrun the game due to problem number 1.
Edit: You know, actually I managed to crash it 5 times in like less than an hour. Something is wrong here. At least this time my saves didn't get deleted
