I was very excited to see commands added in the game, but Ive noticed that not all of them are implemented into the game. For example the command that allows you to keep a baby animal as a animal for forever is not implemented yet, and /summon does not have the skeleton trap summon yet which you need to be able to ride a Skeleton Horse. I hope youre able to complete these soon.
