percent hp (and other tags) not updating

[maven79]

I used a heavily modified oUF_Karma. Many of my tags do not update on player bars, such as HP percentage, or status (offline/afk) unless I re-target a unit or reloadui etc. It does not update on interval or seems to not be tracking an event, I assume. Can someone point me about where or what I might look for to begin tracking down the issue. I've been over the files many times but cannot seem to find the right spot.

Thank you
