I had logged off the other day while running both the Health regen Song and the Stam song. When I logged back in later that day the song was still up and finishing however, I was taking negative hit points instead of gaining. The same was true when you zone over and still playing the song; the song starts to deduct then picks back up. I provided a screen shot. I thought i had taken one with the -2 going above my head but looks like i took it a few secs late, however, you can see it in the chat.
