Received a "Replay OOS Error" after saving a .spr name in Single Player (not hotlap) mode.

Track was AS3, car FBM, with 19 AI set on quick. After a stupid error I sit down for the last few laps and waited for the AIs to end the race, then tried to save the replay. I think not every computer car had already crossed the finish line when I attempted to save, not sure if this should or would make a difference.
