Hi there!  

I keep having an issue when I apply the skin -> it just puts it back to twig, or if I use a hammer, it upgrades to base wood. 

all other skins seem to work just fine!    

I also have the plugin "Build Tools" installed

any help with this would be greatly appreciated! 

Requires facepunch update

Did you alter the plugin .cs file in any way? It isnt working even after installing this morning's server update for me.

I'm sorry to say that this issue remains unresolved.

I did try to alter the .cs but when I added the gingerbread, it broke the frontier skin lol

Had to wipe my image library to fix it so I think something is overlapping somewhere. 

For the time being - I disabled the plugins gingerbread skin so that players could still use the hammer to manually upgrade

how do i disable the plugins gingerbread skin?

Redspyder

how do i disable the plugins gingerbread skin?

Remove the block from the config that sets the icon and skinid of the gingerbread skin and reload the plugin. However, the gingerbread skin will not work even when using the hammer unless the plugin is unloaded from the server

      {
        "Title": "Gingerbread",
        "Url": "https://i.ibb.co/Tw67yBM/gingerbread.png",
        "SkinId": 10226
      }

Ah, thank you, sir.
