The Thieves’ Guild DLC for The Elder Scrolls Online was meant to include a leaderboard reset due to the changes with the Vitality system. Unfortunately, that didn’t quite happen as planned. It was a goof, and it’s been corrected with the most recent patch for the game, which resets the leaderboards to give everyone a fair shot.
The patch also fixes various bugs in dungeons and other encounters, including issues wherein players were not receiving Rewards for the Worthy and Thieves’ Troves weren’t randomly spawning correctly. It should make your time in the game a bit more rewarding and give you a fair chance to climb in that leaderboard for the admiration of your peers.
