Hey StoryAnon,
I built myself a new PC and apparently OoT doesn't move from RenPy saves (should have known since it was Unity) so I redid the game from scratch. I've noticed quite a few issues with this playthough that I haven't seen before. First was on the "freeroam" going to the river would often lock the game. It was the Chapter 28ish? but it would show Sarah on the screen, the grey out and I couldn't interact with it, I had to close the game and restart. Also if you hit any of the buttons on the side auto, skip whatever, the buttons "white out" with literally a big block of white covering them, and pushing another button only moves the white block to that button instead. Another weird issue that I found previously was if you scrolled back with the mouse, sometimes it would roll back to the beginning of the chapter, and scrolling back forward wouldn't bring you forward. Anyways, finished the update a few days ago, it was great. Leah is still gaining on best girl Sarah.
