warcry corpse explode and spectre desecrate

the warcry's cause corpses to explode ancestral commander ascendancy, deathrattle, doesn't explode the corpses of your spectres that are spawned from desecrate, they stay in spectral form.

not sure if this was just a desecrate dd nerf i missed or not

It was changed in 3.25:

"Corpses spawned by the Desecrate and Corpse Walk skills now have a flat 15% chance to match your spectres (or 100% in Hideout areas), rather than a 15% chance on top of being added to the main pool of corpse varieties that can be picked from. These Spectral Corpses are now unusable for most purposes, and can only be used by Minion Skills such as Raise Spectre or Bone Offering."
