WowAce

Deleted all Grid files and reinstalled just to be sure it wasn't a setting on my part and logged in.
Grid2 Vr684
WoW V5.0.4
Sometimes instead of my health being filled with my class color it's black.  Not entirely sure what the error does.

Before this patch I noticed sometimes people with full health would appear in Grid to have a health deficiency which would go away if the missing health was overhealed (since they were at full health) adequately.  Haven't done enough since patch to verify if this is still an issue.

You can download r685 version. Maybe this version will fix the issue.
