I have the barbarian whirlwind with lightning upgrade and the ground stomp with front & back upgrade, yet my barbarian skill unlock is not completed. Has happened multiple times for me in past events too.
Even more frustrating since the ground stomp is a horrible skill (too small of an area and cooldown, and too slow to charge)
