A Painful Bug for Detonate Dead

I'm playing Detonate Dead. To use my skill, i need to target a corpse. If there is anything (such as minions, thin pillars, mobs, or other environmental elements) between me and the corpse i'm targeting i can't use my skill. This is absolutely disgusting for Detonate Dead. This is incredibly painful, especially in rituals, and often makes the skill unusable.

Please fix this.
