Hi. My clan’s ( Dauervoll #GYV0P89P) War Analytics page on RoyaleAPI (Dauervoll #GYV0P89P | River Race Analytics | Clan - RoyaleAPI) shows that one player attacked 17 times during last week’s (115-1) clanwar, even though it should only be possible to attack 16 times.
Not sure whether this is an in game issue or an issue with your website.
