What version of Grid2  are you using (Version is displayed in General/About Tab) ?

3.3.30. (tried the 3.3.31 beta same issue.)

What game client version, classic or retail, windows or mac and language are you using ?

Mac latest client retail

What steps will reproduce the problem?

Power infusion will go secret or hidden during combat; I tested this with tellmewhen and it does not go private in combat at all there so ti might be a bug ?

  
Did you try having Grid2 as the only enabled addon and everything else disabled?

No wouldn't be applicable.

Was it working in a previous version? If yes, which was the last good one?

Not sure just added this in now  

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

No error just goes off the bars in combat.

Please provide any additional information below.

Power infusion is a secret buff that cannot be tracked in combat.

Some addons were using some trick to figure out if the buff was up like detecting the player haste increase, but this was fixed in the latest patch (now players stats like haste are secrets too).  

I dont know if someone figured out another way, but anyway those workarounds are being fixed quickly by blizzard.
