Ruin in 2 waves and NO loot

[daddog]

I just sent a two wave attack against a RUIN. The first wave defeated all of the monsters. My second wave was to carry off all of the loot, but it says that my troops did not find a target. I am not happy that I used all of those first wave troops and defeated the monsters soundly, but got cheated out of the loot. There was only five minutes between the two waves. Do I need to leave some monsters for the second wave next time so that the loot doesn't go away?

Is there a proper way to do a two wave attack on a ruin and get to have the loot?

The first wave is only to weaken the ruins but it must be defeated. If you win, ruins disapear. As an esquire as you are, the single attack is all you need, maybe even better than two. Two wave attack is not usefull till 4 stars...

I did as you said, feeling good that I wouldn't waste troops and get nothing for it again and didn't but I did get a message that the attacked failed to find anything to attack. When I looked on the map that ruin was gone with the normal crumbs remaining. I have been also getting messages about spies looking at my stuff. Could they see that I was attacking a ruin and beat me to it? I am working on counter-spies and a mirror now.

Spies can't see your missions. Only visionaries could.

You should use joint attack option as described here:
