What is happening:
When flying, occasionally, no stamina/energy is lost. (The blue bar with the gem.. thing. No clue what the name is!)
Otherwise, just standing or sitting will cause excessive loss of energy, on some occasions.
(Sometimes, the only way to get it back is to walk around.)
What should be happening:
When flying, energy should be lost slowly and steadily, and regained when standing still.
Steps to reproduce the issue:
Launch, and fly in areas such as Cantermore and the Heartlands (the two most prominent areas of occurrence).
