Solved EchoPet API bug?

Hello, I've been using the EchoPet API lately to create my own Inventory GUI thingy, and I tried using the givePet() method. The pet would spawn fine, but not follow the player. And if the player gets more than 5 blocks away from the pet, it crashes the server. So I tried to use the addGoal() method, but that doesn't seem to work.
Heres the code I use to activate the pet:

Code:

if (getConfig().getBoolean("Players." + player.getUniqueId() +".Pets.MooshroomPet", true)) {
                    getEchoPetAPI().givePet(player, PetType.MUSHROOMCOW, false);
                    getEchoPetAPI().addGoal(getEchoPetAPI().getPet(player), GoalType.FOLLOW_OWNER);

And here is the crash report from when player gets more than 5 blocks from the pet:

Code:
