[Witch] Picking up items with Unearth is almost not doable if there's corpses underneath the item

As title says, I find that trying to pick up items while unearth is bound to the left mouse key is near impossible until you have raised all corpses around that item with unearth. Not sure if this is the right place to post this but just a mild annoyance.

It is the same with Volatile dead that creates an orb of fire from corpses, if a corpse in nearby I can't pick up items.
Would be nice if hovering over an item overrides the spell.
