i entered the game started driving around in Singelplayer, suddenly i noticed i didnt shift by myself, it was on Shifter in options before i started. (im using G25, H-shifter) it had gone back to Auto gearbox. i switched back to Shifter and i drove around for a while, i changed track and left the pits and noticed it had gone back to auto gearbox. i will tell u if it happens again
