Weather Change Results in Rare Lure Mobs to Despawn

This is an isolated problem for skinners. When we spend 10-15 minutes fishing up our rare lures, and then place them, espeically in Zul’Aman, if the weather changes before we kill the rare mob summoned, it will despawn. It bites b/c it takes so long to fish up a lure. I have it happen to me weekly and I’m sick of it.
