I'm not sure if this is a bug but I'm pretty sure it is. Its been 3 days since my leader and 1 of my hero has not returned, it says that they are on expedition when I tried switching leader. But they are not because I can't see them in the army info so that means that they are not traveling, hunting or harvesting or anything. They're just missing... My guildmates told me that they might have been captured but no one attacked me the last time I used thedm. I don't know what to do.
