that type of error usually shows up when you're unable to access MyInstants. All custom taunts are directly loaded from MyInstants. Wait a while and try re-connecting. If the error still persists, make sure you can access "https://www.myinstants.com" using your web browser. If you can access that website through your browser and re-connecting didn't solve the issue feel free to contact me on discord (Martin#6573). Sorry for the inconvenience!
