That's why I've said the BP is understandable, but the leaderboards are not. The BP requires new content, but the leaderboard does not.
From when it started we've had:
1st leaderboard rewards given out weeks BEFORE the season ended. No time or date was given.
2nd was weeks AFTER the season was meant to end, but lined up with the season after it was extended.
3rd was weeks AFTER the season was meant to end, but ended up being before the season ended. (They just randomly stopped it when they felt like it)
So we've got a time critical competition, with a timer that could literally finish at ANY stage of the season. There is literally ZERO reason for this.
Even if it stopped yesterday (as it was meant to) it makes no difference than if it finishes in 20 days.
The prizes do not have to be given out straight away.
