Skin mirroring not working on 1.8.8

[The_SrMega]

English:
Hello, I have downloaded the plugin for version 1.8 (1.0.3-b1670-REL), the problem is that when I use the command / npc mirror it doesn't work, I get the message "(npc name) is now mirroring player skins." , but does not change the skin of the npc. How can I solve it?
