In 1.12 and before, you could create a scoreboard with the player stat, "playOneMinute" by typing in:
/scoreboard objectives add Name stat.playOneMinute
But in the latest current snapshot, 17w48a, if you try to do that, you'll get the unknown criteria error.
While using tab completion, I found that the stat "playOneMinute" was changed to minecraft.custom:minecraft.play_one_minute
However, when I try to use this, I receive
"Unknown criteria minecraft.custom"
Is this a bug? If not, how do I create such an objective?
