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

2.0.22-bcc

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

Burning Crusade Classic, Windows, English

What steps will reproduce the problem?

As a hunter, use Mend Pet to heal pet. Fix is below.

  
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 think the previous version one was working, though I don't remember if I was using a beta version, 2.0.21-beta-bcc, or the previous release, 2.0.14-bcc.

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).

 Don't know if this is an issue I should be opening with LibHealComm or here, but the LibHealComm version I see on Curseforge seems to be a little different. The problem lies on line 1437:

local amount = getBaseHealAmount(hotData, spellName, spellRank)

Notice that getBaseHealAmount takes in a spell id as the third param, so the fix is to change the line to:

local amount = getBaseHealAmount(hotData, spellName, spellID, spellRank)

Maybe fixed in Grid2 2.0.23-beta-bcc version, this version packages the last updates of libhealcomm4 library.

But keep in mind that libhealcomm4 library was discontinued (nobody is maintaining this library anymore) , so probably not more updates and it will soon removed and replaced with the blizzard heal api (waiting for a blizzard fix to a important bug in game heal api).
