I keep getting these espionage mesages. I have 4 in one day. I assumed I was going to be attacked, but it`s been 9 hours since first ``sighting`` is it just because a fleet is just passing by or possibly still comming to me really really slowly. Also is there any way to intercept a fleet on it`s way from one place to another?

From fleet save thread I am going to guess no, but could someone confirm this, thanks!

Seems it is in fact an attack lol gt a message in my overview that it would arrive in 50 mins, but now that message is gone, maybe he recalled.

Well you get that message when someone espionage your planet/moon they will just take a look at your resources and fleet sitting on the ground if it's profitable they'll attack.
So try to stay unprofitable

If you see a fleet coming at you and it is in orange they are probing, if it's red they are attacking, green they are transporting something and blue they are sending there fleet on an acs defend, and in answer to your question about intercepting a fleet if they go to attack you make a note of how long the attack will take to reach your planet/moon and what fleet they are sending, and if your in an alliance or you have friends ask them if they can help you with the attack and if they have the fleet and time they can attempt a ninja. hope this helps you out a bit

Not sure what you mean by``see`` all I get is espionage reports in my messages and they are no colour. Well that 1 time in my overview there was a red cloured one saying I was going to be attacked but it went away. Do you mean the msg in overview cause I really don`t get any there, justwhat my own fleets are doing or is it something else?

The grey ones in your inbox means someone has probed you; basically just checking out what you have, seeing if you're worth attacking.

when you refresh your browser you will see an attack (Red) coming. you can hover the mouse over the fleet section on the attack to see what fleet that player is sending.

If you saw a red mission on your overview it means there was an attack incoming. Since it disappeared it means the attacker recalled the mission. In my overview, I always see espionage missions as red like attacks, so it is possible to confuse the two as well.
