To output lap data from a single player replay, you're supposed to play the replay, hit esc before the desired output lap, and then click on "Output Lap Data".

The trouble is, for a single lap autocross replay, the lap technically already started the instant the replay began playback. So the output lap data function doesn't begin outputting until the lap is finished, thinking it's going to output data for the next lap, which of course never comes.

Any work around or fix for this?
