Neither rollback nor reload fixes the issue. Rollback brings you to the computer screen, so you aren't forced to restart the game. But the error persists if you click on email again.
I see how to add a video or image, but not a file.
Ah, itch.io doesn't allow it. Go to this site where I also have the game and post it there for me? https://f95zone.to/threads/reclusive-bay-v0-16-sacred-sage.81113/page-8
