What version of Grid2 are you using?

 vr916

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

 Windows, game client en 1.13.2

What steps will reproduce the problem?

 Mana bar disappears when converting from party to raid group. Basically in raid group mana bar is not showing.
Did you try having Grid2 as the only enabled addon and everything else disabled?

  No. Since it works in party.

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

  Haven't tried it in raid group before this version.

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).

  I haven't installed them in classic yet. I'll update when i do that if you don't fix the problem before.

Please provide any additional information below.

Working fine here, download the latest version r928-beta, r916 is an old version. If the issue continues, enable lua errors to see the errors messages, and paste errors here, to enable lua errors type into chat:
