I'm seeing achievements fine, but in the last couple days the leaderboard has stopped working. I'm able to ping the stats.hiddenpath.com fine. I was seeing info fine. I've waited overnight to see if it would fix itself as this has happened before. I rebooted, validated the installed.
Thanks for your time!
P.S. Can you remove some of the people from the leaderboard that have impossible scores? Millions of points on some of these is... really not possible.
