My joints have been having issues. Sometimes they work, sometimes they don't. I'll play one game, and have them show up during the replay, but not in game, then they will be on in game, then not. It's very puzzling. Also, my blood seems to be working every time, it's only my joints.
*Note: I only got the joints about two-four days ago, my sleeping schedule has been hell, so I'm not sure.
