EDIT April 1, 2020: We are implementing a fix for affected Alliances which will give full War Chest participation to all members. If you have already collected your War Chest, we will be in contact separately regarding this issue. Please accept our apologies for the inconvenience caused by this.

There is currently a known issue in the game which is causing some players' Alliance War Participation to show the wrong percentage. We are currently working to resolve this issue. Our sincere apologies for any inconvenience caused by this.

If you believe your percentage is not showing correctly, we do recommend waiting before claiming your Alliance War Chest, as this may affect the rewards.
