They said if your werewolf used Lunar Howl they may never be the same again

@Behappy1st I did, and it appears it's a glitch where if their fury level is really high when you do the lunar howl they temporarily lose the ability to switch back to human. It cleared the next time she went on a rampage and I clicked on try to regain control. If you see that your werewolf has the angry moodlet for The Beast Beckons, don't do the lunar howl. I tried several times now with lower fury levels and it hasn't repeated.
