Remember when we say small coding mistakes propagate for the eternity?
There it is: from roughly 2.5 yrs ago: http://myrealracing.club/thread/793/yet-another-fabulous-tt-bug
Now, Juergen brilliantly described a similar feature:
For every TimeTrial that you reset, you also get a re-completion reward.
After you press that reset button, DO NOT run that TT. Restart the game and that TT tab will turn white, and your series completion will drop to 98. Now when you do the TT you'll get the reward (1GC per TT in the Stock Car series)
[Edit: Originally created by Gio, who unselfishly requested it be assigned to Juergen so any reps would go to him. I was happy to comply. --Veyron]
