Hi,
Been scanning the forum and I find this one a serious problem...
Scenario's :
1) Ally/Guildmembers help to take down a city, after it is already conquered some attacks are still incoming.
Ally/Guild could steal that city from you, even though they do not want to, whereas they couldn't have attacked it in the first place if it was already yours when you launched the attack.
2) You sent more attack waves with scholar, but after one of them takes the city, the next one just attacks your own city!
Off course you couldn't have attacked your own city if it was yours when you sent the attack.
I vote for a check when you hit a city to see if it is 'legit', if not, the attack does NOT take place and the troops return to where they came from.
If a non-ally is also attacking at the same time then I could live with the fact that you lost your city,
but a cool down period would also be nice
I hope this get implemented!
