Small update! Various bugs have been fixed, especially ones dealing with the positions of accessories. The Load Character feature also now supports faces.
There is currently an issue with the plugin in Team Create. I have looked into the problem and cannot currently fix it as the issue is on Roblox’s end. A bug report has been made. For now, please use the plugin in a game where Team Create is disabled.
Hopefully the plugin will be up and running again soon!
Team Create appears to be the issue. More info here:
Alright, i’ll make the NPC’s in a separate world where team create is deactivated.
Thank you @Intended_Pun 
In my testing the plugin seems to work in Team Create now. So you should be good to go!
Thanks for the plugin saved me so much time!
im having a weird bug where npcs are teleported to a random location when inserting iterms.
I would like to know if this works with non-humanoid models
the plugin’s ui shows up in game for some reason.
