The incoming attack icon popped up and said realm 8 was being attacked so I moved my resources. When the battle ended, realm 5 was really the one that was attacked. I lost 30,000 resources. Luckily my main resources hadnt arrived yet. What's up with that?
are you sure that you were looking at the right province? 'cause in the attack icon it says also from which province (of the attacker) has the attack been sent, so maybe you were looking at the wrong tab
(i.e. attacker sent his army from HIS prov 8 to YOUR prov 5)
