Sometimes some players see the Leaderboard is not displaying correctly the might or kills gained during an event. E.g. Tournament of Might and Troop Kill Event. On other occasions, the Leaderboard is showing a specific position but the player get rewards from a different tier.
This is normally caused by a synchronization issue between our servers and some players' devices. Despite of fact you observe your efforts are not taken into account, rest assure our log counts correctly the kills and might gained at the end of these events.
If you get rewards from a lower tier when the event has ended, it's mainly because another player or alliance got more points in the end when the final counting is done.
