Icons not working properly

I keep getting issues like this when trying to add an icon/emoji into the group name:

Hi,  are you sure you are using version 1.0.3?

yes most definitely, I've only just purchased the plugin so only have downloaded that version, 

Also been seeing this error a few times, do you know what is causing it?

 Exception while calling NextTick callback (NullReferenceException: Object reference not set to an instance of an object)
at Oxide.Plugins.TCAuth+<>c__DisplayClass26_0.<OnCupboardAuthorize>b__0 () [0x00198] in <d7b017df3d034400aa78124611a8afef>:0
at Oxide.Core.OxideMod.OnFrame (System.Single delta) [0x00051] in <d646191a355d43a6b3ab36b7ee14c740>:0

with regard the icons, I am only getting this issue when using a gradient colour, they work perfectly ok for single colours, just cant add a gradient.

Could you please send me your configuration? Feel free to send it via private message.

The error you are seeing seems to be caused by plugin named TCAuth.
