Hello,
So both of you using custom definitions. Thats the point in common so far.
Please do a small test. Install the "default definitions" and recreate notes then use the HM3 Notecaddy HUD in a small spin n go. Does it update normally with those definitions and HUD? - This will rule out issues with NC install itself.
With your definitions:
This is the behaviour we should focus on: postflop scenario that's played for the first time by opponent in the session, it will stay blank and only update the stat after it's been played again a second time. - Its easier to notice on a new DB.
Please open a support ticket using the "send feedback" button in HM3 and attach there one or two definitions you can notice this kind of behaviour happens. When I have your definitions I will then put them all into a HUD and use a new DB to play a couple spins and test this as well.
Best wishes,
