I'm stuck & need help. Have finished Chapter 8.1, 8.2, and 8.3 and SAVED. I went back to finish Chapter 8 by doing 8.4, but when I enter the door on Flopside Tower, it takes me to CH 8.1 again. I have tried it a number of times, but still takes me to 8.1. I cannot go back through 8.1, 8.2, & 8.3 to get to 8.4 because I have ONLY Mario now. Anyone have a clue as to what has happened that I cannot continue to CH 8.4 ???
