WoW Freakz spell link: https://www.wow-freakz.com/spells.php?spell=43265&&name=death-and-decay
Bug description: The buff duration of the Death and Decay that adds 3 extra targets to Heart Strike while inside the radius ends after the first duration even when standing inside a second cast of Death and Decay. The second duration is not applied or refreshed on the player while inside the radius. Exiting the radius and entering second cast applies the remaining duration of the second cast.

Confirmed . If you get DnD resets while fighting adds and u drop it on same spot or somewhere where they overlap , the buff for hearstrike gets refreshed but it only lasts untill the 1st Death and Decay is over it doesn't last untill the duration of the 2nd DnD is over even tho you're standing in it .
