How can I move an npc after a quest ? I try with the /noppes npc Home  command but after that I move an npc when I try to move it again the command doesn't recognize the npc's name.

It seems the npc is too far away. I think it have to be within your render distance. Maybe the /noppes clone add and /noppes clone spawn commands could be a solution.

Thanks ! And How can I delete an npc with a command ? 

I'm creating my adventure map on a server. When I write /noppes clone list, "server side" is write in the chat. If I put the map solo will the clone still be saved?

Command to delete an npc: /noppes npc npcName delete.

 

Yes, server side clones are stored in a subfolder of the world (.minecraft/saves/[yourWorld]/customnpcs/clones/). When you download the world, the clones are included.

Thanks very much !!!!
