NPC's accessories keep disappearing

I’m trying to make an NPC clone of a player that has all its accessories and such. I insert the NPC into the game fine, however, when I try to move it (manually moving each body part to a specific position, this is an absolute necessity for this game), all its accessories are teleported 100 studs under the map. The body parts are all anchored, and the accessories do move with them, just from a far distance. Is there any way to fix this?
