Hi
I'm trying to give players an item (participation prize) the first time they send us a score (statistic change)
I'm adding a rule for play stream event player_statistic_changed.
But I'm stuck with for the StatisticPreviousValue condition. The first time a statistic is changed, StatisticPreviousValue is null. And the conditions only accept numeric values.
Is there a workaround for this?
Thanks!
