Incase you people were still wondering about why the mod was taken down. And this is an issue I can confirm happens on many occassions (and corrupted several of my saves too). The author themselves stated this as one of the problems on reddit somewhen (I'll look up the link and paste it in this post) describing how newer builds of the Fallout game caused newspawn settlers to just stand around idly, even after being assigned to varios ressources. This problem will spread over to already existing settlers causing the whole population to reach a literal "stand still". This will cause your settlements to break severly, having unfinishable settlement tasks, unworked ressources and a crashed main-story as a result. From there on you can consider your save games corrupted and even deinstalling the mod and starting a new save will utterly break your settlers, forcing people that experienced this to start from a complete clean slate by reinstalling the game and most of their mods. Since most people spend their time within Fallout pursuing adventure and maybe even fail to notice their settlers being idle, this 'bug' is overlooked often but cannot be unseen once seen. *tosses two bottlecaps*
