XBox Console game crashes when Saving/Sharing Tune on Caterham

I made a tune, 750 PI Max allowable for division, upon ‘Saving/Sharing’ Console Crashes.
When I go back, my car still is tuned where I left it, but when I look at the tune, I have an E100 PI Tune with a Red !

Repeated attempts to save and share my tune crash the console, I was able to repeat 7 times.
