After getting everything to create the beach the game moves onto the next chapter however the characters disappear. Wallace only appears when you enter the bedroom. You can hear the Newsagency Lady in the dining room but she doesn't appear and you can't interact with her. You can't get back to the cellar after leaving. You can't get into the kitchen. I have changed to the lowest graphics setting and resolution but the problem still exists.
I had no problems with Bumblebees.
From the other posts it appears other people have got past this point.
