Suggested fix (unconfirmed): Completely uninstall the game, then manually delete its installation folder before reinstalling. Disable all overlays such as Steam, NVIDIA, and Discord.
Suggested fix (unconfirmed): Catch a fish on your very first try during the boat scene with Vicky and Linda. If you miss, load a save before that scene or scroll back using the mouse wheel to try again.
Hello, Thank you for reporting this issue. I've run several tests and unfortunately managed to reproduce the same problem you're experiencing with some older save files.
Suggested fix (unconfirmed): Update the game to the latest version, or contact the developer on Discord to test a deployment build with a newer Ren'Py engine.
