Same happened to me. Was playing and did 21 points for the AMG GT Black Edition in the season and get on 2 days later and hop on and I got reset back to 6 points after that week was over and it took the car from me. Tried to contact support about it but still no reply. Sucks it happened as well cuz I was really hype for this car and at this point dont wanna play the game until its a earnable reward again since support wont help. Would like to see something done since its clearly a issues that happened to players that isnt our doing.
