AFK Mode means it wont click the targets, it will just auto retaliate
Safe spot means it will stand on 1 tile, if it walks off that tile it will walk back.
Could you open the logger and show me what it says. Quest tab is related to OSBots walker, so I'm thinking you are missing a specific item that you should probably have. EIther a burning amulet, glory, ring of dueling, etc

Hey, I wouldnt be surprised if the food option doesnt work at all. You're going to have faster & cheaper trips if you use ring of dueling to goto clan wars. It will reset your stamina to 100.
