I've been playing for like over over 20 hours maybe 30 and my base still has not been attacked.Someone please tell me why ???

I'm over 60 hours in and my food and water are over 30 each, so over 60 total and a defense of only 28 in Sanctuary yet I haven't been attacked once (my one opening is facing the bridge with 3 heavy turrets and 2 guard posts). Something tells me that something is very broken, because I'm a prime target yet no raiders in sight... and to be honest, that's the element of base building that I've wanted to see the most.

When your defense rating is too low it should become red. So if you set up a dozen turrets and traps around your settlement waiting for raiders, they won't come. But if it goes red, then attacks may randomly occur when you're off doing something else.

I've not had Sanctuary attacked yet but the smaller settlements have been attacked occasionally, it usually happens right when I'm in the middle of something. I suppose since I have like 7 settlements up and well maybe not running but at least allied then my chances of being attacked are higher.

I have seen sanctuary attacked once. While I was there doing some crafting and by a single raider against my 12 heavy turrets.

On the other side of the bridge from Sanctuary Hills, I found a couple of dead Raiders. I only had a couple of Machine Gun Turrets. So it possible that they attack even when you aren't around.

Well, I had my base attacked and they damaged 3 turrets, a generator, several of the defense platforms, and 3 plants and who knows if they stole anything. The thing is, I never got any warnings to go defend. I just walked in and found stuff needing repair.

Defense: 75 (dropped to 45 after attack that is how I knew something happened)
Food: 19
Water: 15
Residents: 8 (1 died)

I have no idea what happened. I am playing on survivor (because the game is way too easy).

I'd like either a mod or something in an official patch update that makes attacks happen now and then even if it's futile for the raiders to do so. Hey, its' a desperate world. Maybe they were driven to madness by hunger and thirst so they chose suicide by Sanctuary. My food and water is significantly higher than my defense rating and yet after 20 hrs I haven't been attacked once.

It would be nice to know what the triggers are. I'm happy so far in that none of my settlements have been attacked. I don't really want to have to deal with that yet.

Yea the only warning you get is a quick popup in the top left of the screen like a quest updating, easy to miss if you're busy
