Steps:
1. Create a Macro that contains the line: /pet "Somersault" <me>
2. Call the pet HeadBreakerKen
3. Try to use macro
4. Macro fails with command error.
5. However, you can use the Somersault ready move from the menu, just not from macro
I had another person playing on Xbox verify it fails for him too - so it is not just on PC.

/pet "Somersault " <me> work (with an extra space at the end).
