Your mission gameplay rank MAY BE ERASED!   If you play the final casino mission (and you are NOT the host) your play history MAY be wiped and you could be re-set all the way back to the very first mission. All of your progress- GONE. No fancy car. Back to square one. This is a KNOWN ISSUE. Do not play the final Casino Mission (unless you are the host) because you MAY lose all progress. Fingers crossed this bug is squashed soon. Boo hiss.   PS4PRO
