Hmm did you reset and then reprocess your notes? http://wiki.assaultware.com/How-to-r...ddy-notes.ashx
After doing that you can right-click on the definition in NoteCaddy and click Analyze. Then you can go into the Recipients tab, and find someone with some instances and opportunities. Then check that player in the HM2 replayer to see if the stat appears for him/her.
