Fallout 4 Ppf.esm -

Objects pop in and out of existence as the visibility system breaks.

The "story" of PPF.esm begins with a fundamental flaw in the Commonwealth's reality. Bethesda built the game using —clusters of objects like trash, trees, and buildings glued together to help the game run smoothly. When mods try to "clean up" the wasteland or add new buildings, they often break these clusters, causing a glitchy phenomenon where buildings flicker in and out of existence, known to modders as the "void".
