People losing sync and flying in mid-air almost always happens when something forces me to load in slower than normal, like say 190 people being on the server with the graphics maxed. A cool thing though is that when the person gets dehorsed they become resynced, so it is possible to resync after the match starts. Would be cool to have it resync at the first tick of the match to help people out even if it isn't a true server side problem.
