Translations:NPC Placement and Alignment/63/en
From DragonMineZ Wiki
Quest NPCs (Bulma, Krillin, Yamcha, Tien, Piccolo, Gohan, Vegeta, Trunks, Chi-Chi, Videl, Shin and the Namek Elder) appear in the default file too, but with "enabled": false: they are no longer spawned at runtime through this system. They are baked directly into the structure NBT, so they live at fixed, hand-placed spots instead of piling up at the world spawn. Their entries here are for reference only. NPCs added to a structure after its NBT was made come from structure NPC files instead (Chi-Chi in Goku's House is one).
