Shard storm breaks blight caster's hive master's visuals

Bug Report Number:

320682

Using shard storm on a blight caster in hive master form will break the form's visual look until toggled off and back on. I didn't have a video to include with my bug report, so posting it here; can see how after shard storm wears off that the visual looks different than at the start of the video.
