Just throwing in my bit; same problem, joined an online drift lobby post-1.05 and since then I'm unable to change any settings on the fly barring ABS, F/R power for 4WD's, and brake balance. Going into a race or practice to find TCS has defaulted back to 5 (which is happening a lot though I can't point to specifics right now), and then having to come out of the race and change it in the settings again is a complete pain in the behind.
Edit (random idea): Has anyone tried creating a lobby with all options enabled to see if this fixes the problem? I will, next I'm able.
