They really need to do something about settlements being attacked when you have a high defense rating and still failing when you're not there. My last attack I didn't even get notified until a failed to defend message came across my screen. This is a settlement with over 100 in defense, all my settlers have good weapons, most of it is walled off and yet it fails because I wasn't there. What's the point in investing in these turrets, guards and walls if its going to fail because your almighty presence wasn't there. Especially when you weren't notified. That's my major beef with settlements.
