I'm trying to do something epic by robbing these Viper fellas while they sleep. Problem is, they never seem to sleep. Anyone have any tips? Around what hours, if at all, do they sleep?

You occasionally see some of them sleep as you come across their camps; however, I don't think I've ever seen all of them asleep at once.

Which actually makes sense; they wouldn't have gone to sleep without someone keeping watch.

Thanks Golem, I'm wondering if the AI actually factors that in at all. When there's three of them I can't get any of them to sleep at all. When there's five I've seen one sleep. I think I'll take this over to the mod forum because this section probably isn't based on technical knowledge.
