Please help! 🙏

So I've been trying to finish the new Ms. P quest, but I keep running into the same problem: when I'm collecting the puzzle pieces in chapter 12, one is always missing. The top right corner of the picture, which (at least for me) spawns at the green location on the side of the railing. It's not that I can't find it, because I know where to look. It's always this specific one, and even if I restart the game and do everything from the beginning it's still missing. Has anyone had that problem too? Is it a bug or am I doing something wrong? Please send help 🙏
