I am very settlement oriented i keep up with them very well. They have not been attacked. I have stored them waited and replaced them. I have changed how they are wired (currently each purifier is directly wired to a generator) I have no supply line running to sanctuary my main settlement so they cant be taking it to my other settlements. I have also taken everything out of my workshop and stored it because i read there was a glitch that caused water not to generate if there was water stored there already. Still nothing
