If you haven't played NFM 1 and 2 for a while (usually about a week), the game's save data will be gone, and you will have to restart the game all over and you will have to unlock the cars all over again. This could be considered the most annoying glitch of all. Why this happens, might be because Java erases the temp data up to a certain limit of data, and the save data is located in it; or it might be a glitch in the game; reason is unknown. It happens on both the online versions, and downloaded versions.
