had a core.exe crash and restarted the game. but instead of the bike that i used in the last session (wsbk17) the yamaha m1 was shown in the garage/main menu. when i clicked somewhere it flickered and got replaced by the correct bike (aprilia rsv4).
so i am wondering if gp bikes just leaves random, unnecessary files in memory?
Yes very possible. Few times I got a core.exe crash during online racing I saw +1person in lobby and I couldn't connect. I have to close the game and run it again or try few times to reconnect to the lobby.
