Translations:NPC Placement and Alignment/8/en
From DragonMineZ Wiki
Both files are only written with DragonMineZ's defaults when they are missing. A world created with an older DragonMineZ version keeps its old files, so it does not get new default entries (for example the v2.2 Otherworld NPCs and their new coordinates). To get the current defaults, delete the file (back it up first if you edited it) and run /dmzreload config.
