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

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

What steps will reproduce the problem? Anytime when i casting Prayer of Healing

  
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? I don't know. I've got the second T4 piece yesterday only. While I'm wear, the Grid2 pop a LUA error when i cast Prayer of Healing. Because the T4 setbonus provides a Hot (Renewal) when cast PoH, I think the addon can't manage this. 

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).

Please provide any additional information below.

The LUA error:
