How close were you to the skeleton?

According to the wiki, close enough for them to see me. Thanks for posting that, I didn't know that invis worked like that before this.
I was sure this was a bug because true invis gets rid of armor and held items. I assumed that this meant that the detection range taking into account armor and held items would be equal to that of normal invis without any armor no matter what. I was wrong.
