Stuck in Pokepon (1.2.7 Core) (FIXED)

I’ve read through a number of topics about this issue but still can’t figure out how to solve it for myself. I’m using 1.2.7, everything should be up to date, but I’m stuck immediately after the Pokepon attendant moves into the fence. Loading backup saves didn’t work, and for some reason a new backup is created every time I check to see if it’s fixed (so all my backups are now the glitch.) Is this possible to fix? I’ve been playing side-by-side with my brother and starting over would suck.

Edit: Downloading and running the 1.2.5 core worked, for anyone else who experiences this.
