I have a mod that's working in the editor, but when I go to export it it seems like the game is overwriting my script files.

I made changes to BestiaryMenu.tscn and BestiaryMenu.gd, and while I can see the changes from the tscn, any new methods I define and link don't get called, while I can call existing methods fine, even from new buttons I create. It's especially strange because I still see this when I duplicate those files and try to load the copies of the scenes/script instead-- I still see visual changes, but no mechanical changes. Does anyone know what might be going on here?
