Good morning,
During the performance of the career in sharing with another user in the "two players career" mode, arrived at the Grand Prix No. 15, it’s not possible to enter the headquarters where to continue the career. Specifically only a user can enter, while the other remains in the "loading" screen.
If the player who has managed to access returns to the main menu, the other can access the headquarters but finds himself in a different Grand Prix and the advance command is not displayed to continue the career.
This happened at the beginning of the Holland Grand Prix.
Platform: both players on PS4
