When Hatt takes flight, the roll ability cannot be used immediately.

When I control Hatt and take off, I cannot use the Roll ability immediately. The Roll button is gray and does nothing when clicked. However, Wing Strike works properly and its button is lit.

When I was playing as Hatt and took flight, I couldn’t use the Roll ability. The button was grey and did not respond to taps. I have to wait about half a second to one second before it becomes usable. However, Wing Strike works fine and its button stays lit.

The Roll skill should be available and its button lit the instant I take flight. Instead, Roll cannot be used after takeoff, but Wing Strike is lit up and works normally.
