There is no such thing a player to not get any loot at all. This is only what is listed, not the reality. And it is listed the owner didn’t lose resources, not that the raider didn’t get.
I will get tired eventually of how many times I explained before, how the raids, revenges and watchtower work
The thing you (you, all viwers, not yelnats) all need to know, there is no such thing as available loot food 0 iron 0. Any player gets something, raid or revenge. But in revenges, if the attacker has emptied the tower before attacking you, in his tower log will appear you didn’t get resources at all on revenge; but you did, obviously.
Let me clarify once more. Every time a player enters raid icon, in the downside of the page is written “my watchtower”. That is the loot the player who got attacked, will take back from you, the attacker. If you empty the tower and attack, then in your tower log will appear the avenger got no resources, only the trophies from you. But this is not true. The minimum loot in the game is 4k food and 2k iron. Resources the avenger will get if revenge is successful. But not the resources you lost. Because you lose nothing, in fact.
And the second important thing is: anytime you go offline, first empty the tower. No matter how many times you get attacked, you lose nothing. Only the attackers get loot, the owner doesn’t lose it actually.
I know @DracoLovesRi said at other thread few days ago something has changed, but I should have noticed. Nothing has changed, at least for my two accounts. I always find the right amount of resources in my tower.
Now, from my understanding, OP says is no problem with that. But after he goes online and he gets attacked in the first minutes, he loses the resources (because he didn’t empty the tower when entered the game). Now, I will say again, this never happened to me, though I was attacked after minutes I went online. The reason is simple. The raider began his attack while you were offline and finished when you were online. However, this changes nothing. Because when he started the attack, he already had displayed the available loot (which is minimum, if you emptied the tower before went offline). So he cannot gain more than he had displayed, neither you lose something.
Again, if something changed, I would have noticed
