What version of Grid2 are you using?

 r939 (Classic)

What game client version (windows or mac) and language are you using ?

 1.13.2 (Classic) on Windows 

What steps will reproduce the problem?

I am not able to consistently reproduce the issue but it happens at least 2-3 times per dungeon/raid  

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

No

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

Not sure

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 errors that I can see

Please provide any additional information below.

Occasionally Grid2 reports a players health incorrectly. This leads me to healing a target who is already at full HP. See below from my screenshot that the player "Hotburrito" is missing 625 HP according to Grid2 but Shadow Unit Frames is reporting he has full HP (none missing). No buffs/debuffs were recently removed either. Once I heal the target, Grid2 will then update to report the correct HP. I am unsure if this is a misconfiguration of Grid2 on my part or a bug.

1. Which type of health update configuration are you using ?

Statuses->Health&heals>Update frequency

Normal or Instant ?

Instant option is not always accurate, because is a estimate of future health based on combat log info.

I am using instant, I will try with Normal and see if that corrects the issue.

Setting it to Normal seems to have fixed the issue. If I notice the problem reappear I'll reopen the issue.
