I recently bought the dirt rally 2.0 game of the year edition in the spring sale. I installed the game with all it's dlc's and launched it with the profile which bought the game. Everything works fine with this profile. But when I launch the game with an other profile on the same Xbox then the game doesn't work correctly. First of all, the icon in the upper right corner doesn't change to the season 4 icon. Secondly, all of the dlc rallys like Finnland, Sweden, Germany... don't appear in the career mode, but they appear in the career mode on the Xbox profile which bought the game. I don't know why this happens because I have access to all of the dlc cars and rallys in time trail with all profiles.
