All donations should be recorded, including the ones you donated to the war clan castles. Our clan is having issues with this, as we know people aren't donating to the war castles. You should also receive xp for doing so. This would help our clan to show the people who aren't donating to war castles. This would also help out the game as well. This idea should be put into consideration, as it will help clans and also gain more xp for players.
