Explain:
^ added that myself sorry! Anyways I always see the blank aura (Like where an buff/debuff could be but its like a spot that looks like an empty space) on the target frame a lot, not very annoying but I know its fixable. Any chance this will be addressed in the future? If not I understand! Thank you for the great UI
