Diablo 3 Leaderboard API does not return BattleTag

Currently the api /data/d3/season/:id/leaderboard/:leaderboard does not return hero BattleTag anymore.

This is clearly a bug, and if you go to rankings on the d3 official web such as https://us.diablo3.com/en-us/rankings/season/21/rift-barbarian, there’s no BattleTag either.
