Single player -> Leaderboard challenge -> G27 dont work at all. No wheel, no pedals, no shifter. Pressing ESC, going to Options->Controls - all axises moving OK, back to game - G27 dont work at all. Multiplayer mode works fine
I am on g27 and I have a number of entries in the leaderboard. Are you ok to play single player practise, or race?
Any chance it was the Hillclimb? That one was bugged indeed, but should be fine now with the latest update: "Fixed Hillclimb stages start phase that failed to hand over control to player"
