The top 3 people's ghosts never finish the race.. They are all on mobile as well. http://www.freeriderhd.com/t/2766-bunnyhop
Do you have some other examples? We are aware of a bug with "boosts" that may break replays on certain devices (ie. a windows phone replay may not work on chrome / PC). We do have a plan to fix but it will have to be for new tracks once fix is released. There are no boosts on this track which leads me to believe it is an issue with restarting not being picked up properly but will have to look through the replay code to be sure.
What's wrong with this ghost then? http://www.freeriderhd.com/t/53559-ninja-on-a-bike/r/jared951 His ghost isn't made on mobile and the restarts work fine, eventually it seems that his ghost isn't synced with what keys he was pressing.
Here is a perfect example of it. Watch all 10 of them at the same time. http://www.freeriderhd.com/t/10253-the-speedpark
This is weird. Watch the timer time. It ends at about 13 seconds, but on the leaderboard it says 11.70. http://www.freeriderhd.com/t/52789-wood-slopestyle/r/skijumping
Char It happened again! It happened to me! In the global best times it says I got 5.00. In the friends best times it says I got 5.23. If you click on my name in the global best times, you can tell that I finish at 5.23! The link to the track is here. http://www.freeriderhd.com/t/56414-extreme-cannon EDIT: Eric This might concern you too.
