For whatever reason, UnitAura(unit, spell, "HARMFUL") does not seem to equal UnitDebuff(unit, spell). While the latter gives correct returns, UnitAura with "HARMFUL" does not. I am using it with spell names rather than iterating over the indicies. Any idea what I might be screwing up? (Not using it in oUF tags but this thread was the closest I could google up on the issue.)
