Back when I was messing about with this OOB I managed to a sequence break into a San Bakar's Trial Pensieve camber to unlock the "The One Who Mastered Memories (View all Pensive memories)" achievement early. Although when I interacted with it there was no cutscene, the achievement just popped up. I didn't want to screw up my playthrough though, so I went to a savefile before interacting with the memory. I don't know if it could've been any useful, or just messing up the game cause I didn't look into it further than that, but it could be interesting if anyone who does speedrun the game could look into it and see if that sequence break could be any useful or not! :)
Here's the video and attached image of the location in case of confusion! https://imgur.com/a/V9GIZ9O I've had some fun exploring with this glitch, but maybe it could be of help with the speedrun community!
Glhf everyone! 🙂
