Revisiting Bae tickling with Nessa in the video room, at the end of the scene I get an "error to Load" issue which stops progression and keeps popping up, forcing me to close the game.

Oh, I see! It's a common bug that happens when you do not have the right alphabet/keyboard installed in your PC (your PC doesn't like the accent in Pokémon, basically). There is a really simple fix. I've uploaded several fixed versions of the OST files that can cause this in the thread, so you put the files in (in BGM in the game directory), and it should work fine. You can also just rename the OST file mentioned and get rid of the 'é' in Pokémon and it should work too.
