In addition to the previous protections, now is no longer possible to shear sheep or mooshrooms on islands you’re not a member of.
And… only white sheep can be dyed. If that sheep has another color, re-dyeing it is not possible for *anyone* including island members. This is primarily to protect those that buy lapis with real money and want to keep them blue from anyone else.
Enjoy a safer skyblock! 🙂
