Unable To loot when equipped with certain skills

Equipping Volatile Dead casts fireballs instead of looting when mouse highlights the loot. This was the wand used. Corpse needs to be cleared off in order to loot.

Updating on this, a friend of mine playing had a similar issue, but with Unearth. It seems that on WSAD move, the game prioritizes any skill that interacts with corpses over looting.

The work around I found is just moving that skill to a non-left click option. However, this is a negative space that should be looked into what's causing the issue.

It should only use the skill, if there is a corpse under the mouse cursor - otherwise walk to the position or take up items from the ground.
