Well, when the 1.6.1 came out I started playing then I put a name tag on the horse and then it went upside down.
It is a server i am playing on and it's fun good community! Do you like the horse update because I do a lot!
I tried doing upside down horse fight and race you should try it! Just put nick name on them and it will go upside down!

If you want to know what server messege me!
