OK, first thing with Mia story is that you have to talk to Helen. Do this in the afternoon, in Mia's house, second floor, Helen's room. Ask about the wiping. This will allow to proceed further. Be warned that you have to advance Erik's story to return the stolen goods to Harold not much later.
For Clyde to return, I would suggest you advance Roxxy's story first. You will also have to advance Consuela's story.
Finally, for Mrs. Johnson you first need to get introduced to Anne in the Gym. Find and return her dog when meeting her again in the park.
I played all this with your save, no bugs there.
