To fix the P2 glitch thing, do a lap on the other set of prime tyre*They have NOT fixed the Multiplayer SC
*It now has bugged the tyres in GP mode where tyres you dont use get worn to the same amount that the ones you have used, which means going into practice 2 when you should have a brand new set of tyres, you dont as that set is worn so that limits your running.
all the rest I think has been fixed (from memory)
