I've been stuck at SR-70 for about 3 weeks and I had like 30-50 more match left so I can't gain double exp. well today I put in the code and all my double exp are wasted from me still playing when I was SR-70 I wish I knew that when you max out your double exp is wasted. When I finished game it didn't show the exp so I thought it didn't waste them because you can't double exp nothing.
