Hi, I finished every challenge in Hitman Absolution without a problem except for the challenge in the vixen club: Schadenfreude; I managed to drop the disco ball on the target's head multiple times although it was difficult to time it right on the PC as anyone who played it on a PC knows, not as easy as on a console, yet the challenge did not register. I have tried all possibe situations for example: kill or subdue the guard in the back room where the button is while wearing a disguise, shoot the ball, do it dressed as a cop, or do it with the suit without knocking anyone out and remain undetected, it still did not register as complete.
As a perfectionist I'm going crazy here someone give me a solution please. Thank you.
