What is happening:
When I choose combat as my talent, and go to seek training from Reefus Clackett and Icy Sheets, I am instructed to perform a seismic buck on Clackett. Unfortunately, there is no seismic buck ability listed in my journal for me to drag to the hotbar. I have checked under all the tabs but all I see in my abilities is the basic bubble barrage, and ground pound.

What should be happening:
The LoE wiki tells me that to equip Seismic Buck, use the book on the bottom right of the screen, and drag the spell onto the hotbar

Steps to reproduce the issue:
Played through the tutorial as an Earth pony and went directly to choosing my talent. I then went straight to Cantermore, to train. I have tried this as a Pegasus, with the same results.
Also, as a pegasus and an Earth pony, I have played through the wolf-pony quests, yielding the same results.
