Hi,

when I was fighting a usurper the fleet of the usurper was NOT shown in the list for enemy fleets. I did NOT recall my fleet or did anything else that would prevent it from being shown.
If this happens with a players fleet it is a real problem.

When you attack some fleet, it's not shown in the menu.

This confuses me.
Because every pirate fleet I ever attacked was shown in the menu under "enemy fleet".

Like this: http://prntscr.com/o287ai

But in the screenshot of my first post I was battling a pirate fleet and the fleet did not show up in the list for enemy fleets. There it says "Enemy 0".

When you attack some fleet with mission Attack, it's not shown in the menu)

Ok,

I realize the difference between when it's shown and when not but is it really necessary to hide the enemy fleet from the player during mission attack?

This has additional downsides too:
-The player can not follow the battle without attending it.
-No sound notification for the attacking player when the battle starts. You have to be there and never doing other things (like reading the forum).
-Without any notification it happens that the player misses the initial 10 seconds that specially are designated for the player to join before the battle starts. I can't join the battle when I don't know about the battle. :/

Done. There is a checkbox in fleet send form for mission Attack and some other missions.
