We watched season 1 in the fall until it suddenly stopped..not sure how many episodes last Sunday there were 3 episodes which aired called new. I taped these thinking they were season 5 Although new to me they were of season 3 being shown this month until the 29th Season 4 ??????? Season 5 starts in Nov. ??? There is not enough preparation for the public A chart showing available episodes where and when would be helpful from season 1- 5
