Recently noticed this issue. At first I thought it was creator specific, but it's for any downloads that are proper car files directly downloaded from Stunod (i.e. not linked out to mediafire, not a .rar, etc). The file name is automatically given an extra space following the series designation, so when downloaded, the file name is "carname.cup .car". This space doesn't keep the car from appearing in game, *but* it does make it act like a corrupted car file. I don't mind manually deleting the space myself when I download, but I thought the site admins might want the heads up anyway in case of further complaint.
