@EA_Illium I can confirm what @packattack04082 said. Today the leaderboards were wiped for two out of the four Daily tournaments and the Weekly Pro leaderboard has been reset as well. Obviously getting no prizes for those because the game shows it as an incomplete attempt.
Original scores are still missing from the Weekly Arcade leaderboard, which is what caused me to make the original post yesterday. With the Weekly Pro entries disappearing today, I am assuming the pattern will continue and we'll wake up tomorrow to find the Weekly Tour leaderboards have been wiped out. That'll be especially annoying since I'm sitting T1 and won't have time after the weekend for another attempt.
Honestly it's frustrating seeing things like this happen because tournaments are the only online game mode worth playing on PC. The number of players entering tournaments is dropping rapidly. Losing scores is only going to further drive people away, especially having paid tickets to enter.
Hopefully tournament scores are backed up and the leaderboards will be reconstructed. Although given that we never saw any follow-up or resolution for past tournament issues (like this EA PGA tweet suggested), I'm not expecting anything...
