15. crouching while playing a bard song results in the song stopping, and your endurance bar dropping immediately to zero.
** Confirmed **
And it's worse
Crouching makes the spell gem go active as if the spell has stopped, but the song keeps playing, and trying to cast a new song doesn't work, just displays "Your song ends." There's no obvious way to stop the song.
After #kill the song buff icon is still on at 24sec frozen.
The dropping of endurance bar only happened once to me, and it was reset back to full when i tried to recast song.
Also, when playing a bard song and stopping it on purpose, the "Your song ends." message is displayed 4 times instead of once.
