Hello Viperz King,

It appears as if your resource pack has not loaded in properly, try relogging and making sure you have resource packs set to prompt and that you are playing on either 1.10.2 or 1.11.2. I hope this helps, if you have any other questions feel free to message me on discord or on the forums!

 

I am using the twitch app to play. Could have something to do with it because it not working still
