Mag - Magnetize Sound Timing Issue

[(XBOX)RedShinigami83]

One of the sounds associated with Mag's Magnetize ability plays at the wrong time whenever you increase the duration of Mag's abilities. The sound in question plays when the Magnetize bubble ends by shrinking and disappearing, prior to exploding.

With normal duration, the sound plays precisely when the bubble ends - 15 seconds after casting. However, when Mag's duration is increased, the sound still plays at 15 seconds, even though the actual bubble doesn't end until 20 seconds.

Can you please fix the timing so that the sound plays whenever the bubble ends instead of only at 15 seconds?
