That's super weird :/ Maybe the issue is with the version you're using, then? I didn't actually use Squirrels as a base when I made the hack, I just made an .ips patch with Squirrels, as well, because that seemed like the one most people had access to. If at all possible, maybe try using a different FireRed base and one of the other patches I've provided? Your save file should still work with it, after all. Other than that, I'm afraid I'm out of options.
