It sometimes (not 100%) happen when someone dies in the group.

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

Yes

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

Yes

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 whatsoever

Please provide any additional information below.

Here is a screen on Gyazo to show you the problematic frame. You will see that "Sylendae" isn't counted as Dead (usually, the frame is black, and DEAD is shown in place of the missing health) :

Thank you in advance ! :)

Are you using a "multibar" or a standard "bar" indicator ?

What kind of health update frequency are you using ? Normal or Instant ?

I think it's a standard bar indicator (if you know where I could confirm that, I must admit that I don't see the option right now ?)

The update frequency is instant.

The weird thing is it's happening totally randomly, like when there's a wipe in a 20-raid, I'll see 4 to 5 people with the bugged frame, the others will work well (experienced that yesterday, so I just wanna add this information) :/

The dead indicator is straigth forward, it seems ocassionally the game is providing wrong information to the addon. Are you sure no lua error is happening ?

Yes I'm certain, no LUA error at all unfortunately :/

I update this post because the problem seems to have disappeared by itself since the prepatch (never noticed it since).

As you said, maybe it was just on the Blizzard-side, anyway all is working like a charm right now, so I can close this issue !

Thank you for your previous answers and searching ! :)
