This episode happens to be my favorite one. The reason why Mrs. Oleson is not in it is because (if you have ever seen it) she is in the hospital in Minneapolis. She has been in there for 6 months. But Katherine McGregor (the person who plays her) was on a pilgrimage for India. I would recommend watching it, especially if you have seen the rest of the series, because I feel that I the best of them all.
