I'm playing on Mac.
Ah, no I didn't, I missed it! I'll try and run it again tomorrow to see if that fixes the problem. Thank you!
It turns out there's no "Show Package Contents" popup when I right-click the folder.
Edit: Nevermind! Looked through the comments and found you helped someone else with this and used that method. It worked and I can now use the options menu!
Thank you for your patience!
