Was the race restarted? If it was the replay of the end of the event would be ok. Then no one involved in that race was on autosave? That's a tip that Josh usually give to prevent such failure. When I was running lfses, after almost the same problem ( i managed to find someone who saved it) i asked 3 different guys to save it in case of that (autosave)
I will only add competitions & events for which you are able to provide all of the replays. It isn't acceptable to simply exclude sessions for which you have not saved replays.
I will add any events for which you have replays, and I will add future events. Please post a new schedule which contains only events meeting those criteria. I understand that your competition runs indefinitely; you do not need to group events into 'decades'.
