I tried to export to windows, but I didn't realise godot's PCK system was case sensitive, so I had to refactor many filenames to lowercase. However, after refactoring the names, removing all scripts/scenes from my scenes and preloads and reattaching the ones with lowercase, I still get the above errors and I can't find any documentation on what most of them mean. My game does export and starts, but almost all functionality doesn't work (the camera follows the cursor, and my character faces the cursor, that's it...)
just to be clear: these files marked in the purple errors do exist and are in the correct folder, except for the Playermovement.gd and the Dummy.gd, those are in fact gone, however no code or Node is referencing to them.
