I found a "fix" to the Halloween update for android users.
Delete the current dawn chorus version on your phone and reinstall the Rune update.
DISCLAIMER: 1 you will lose all your progress so only do this if you don't mind rereading the story.
2 if you also have the Dawn Chorus app in a secret folder it will refuse to update so delete it from there too
or you could just wait for the devs to release a proper fix.
