It could be just assets that they need to be in the zone to utilize. In another game some players found a way to get outside of the playable boundaries of the zone map and found assets outside of the map. These were things that was used in cinematic clips. Also, players found npc copies of their character.
Basically, due to the way that game was designed they required the assists to be loaded into the zone to display them in cinematic clips. This included the player’s character. A clone npc was made when players zoned in, so later they could animate npc clone in the cinematic clip.
It also explained why they lowered the number of players that could be in one given instance for a zone, because the zone was creating these temporary clones for every player that zoned in.
They stack assets in the same place because that becomes the known coordinate location for the assets. And for some games it keeps them from being calculated during rendering because they are outside of the player’s rendering distance.
