Noticed that players that you have made 'friends' with can be attacked according to profile pages, yet when a 'friend' also sends a fleet against the same pirate then player is listed as an ally.
If you win the battle with the pirate is the 'friend' still an ally if they arrive after the battle, or during the battle ?
Surely anybody listed as a friend is automatically a defacto ally and should be placed in the 'cannot attack' position
