Game glitch

My game keeps putting me thought the same missions over and over-and keeps making me wait for calls I've already had-AND this ateast thing with the coupe rivalry with Chad Dylan and co has lost me like almost ten million. Fans because the game keeps putting me bk to the the start of the rivalry and more ago grand despite my having left gone thru it. And when I was in the middle of the watch party (hadn't even finished it) I got a call from Simon saying if lost the contract for the watches-the job wasn't even complete! And now it's just lost me another 700.000 fans because Chad Dylan thing started from the beginning again. Why does the game keep doing this?
And I've had about twenty or so calls from Simon telling me about the movie with Chad Dylan. What on earth is going in? I'm loosing fans for things that I've done over and over again (the same thing over and over) and I've lost cash, stars and progress as a result of these glitch wax
Anyone else having these problems?
