What version of Grid2 and game type (classic or retail) are you using ?

 1.0.0.zip

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

 Windows English

What steps will reproduce the problem?

 I dont know, it only happens with specific users that will dissapear once the instance (rbg) starts. they appear in the unit frames again once you are out of it...
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?

  I dont know

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

Please provide any additional information below.

It has happened often, its not a one time thing, sometimes some persons in the raid dissapear from the unit frames after loading into the RBG, and no matter how many times u reload UI, or relog it keeps happening with the same persons. I had to change the UI addon Grid2 for another one to be able to continue, but I would love to keep usign Grid2 if this gets fixed. 

Looks like this old game bug:

Are the non visible units displayed as "Unknown entities" in blizzard raid frames ?

Is the issue fixed when you get out of combat ?

No, they simply dont exist,  it doesn't say unknown or anything,  simply they are not there. And it won't fix at all at any point during the bg. Only once you are out, and if you go into another bg, the same person dissapears from the grid.

I was asking about "blizzard raid frames", not Grid2. I want to know how those players are displayed in another raid frames.
