Tall grass around the bench. Also this bug has been reported twice so far, however I am not sure what causes it, I'll have to get someone's save game where they are stuck otherwise I can't see how and why it wouldn't work.
I have that bug it you haven't gotten the save file yet I can get it to you. I'm using the android version btw
It should be fixed in the latest bugfix.
Music to my ears.
