Solved MundoSK displayed skin?

[itsAaron_]

So, I've been trying to experiment with MundoSK's tab features and "displayed skin" features; I was able to get the tab to work with a custom "old" skin (see code below).

        set {_value} to yaml value "classes.%{dnd::players::%uuid of player%::1::class}%.%{dnd::players::%uuid of player%::1::gender}%.value" from "plugins/Skript/scripts/configs/classes.yml"
        set {_signature} to yaml value "classes.%{dnd::players::%uuid of player%::1::class}%.%{dnd::players::%uuid of player%::1::gender}%.signature" from "plugins/Skript/scripts/configs/classes.yml"
        set {_skin} to skin with value {_value} signature {_signature}
        set amount of columns in player's array tablist to 4
        set amount of rows in player's tablist to 20
        set display name of tab 1, 1 for player to "{@prefix}"
        set icon of tab 1, 2 for player to {_skin}

However, using the same method I cannot get the "displayed skin" feature to work.

        set {_value} to yaml value "classes.%{dnd::players::%uuid of player%::1::class}%.%{dnd::players::%uuid of player%::1::gender}%.value" from "plugins/Skript/scripts/configs/classes.yml"
        set {_signature} to yaml value "classes.%{dnd::players::%uuid of player%::1::class}%.%{dnd::players::%uuid of player%::1::gender}%.signature" from "plugins/Skript/scripts/configs/classes.yml"
        set {_skin} to skin texture with value {_value} signature {_signature}
        wait 5 ticks
        set player's displayed skin to {_skin}

I have no errors, though the skin doesn't change. Would appreciate any suggestions, thanks!
