Issue #26800: Shouts Interrupted
I have discovered that shouts can be interrupted during combat due to unknown reasons.
After pressing the 'Power' button to activate an equipped shout, the first word of powers audio file (in this case Fus & Yol) is played but the shout is immediately disabled and my character is unable to do anything for a very short period of time. Sometimes the shout can be used again straight away, sometimes it can't.
