The addon fails to load or function in the patch. Would love to know how you fixed this once you find the problem:

Here are my bugsacks errors:

}

I was able to workaround this one by removing all three instances of CharCustomizeFrameWithTooltipTemplate.

The next error occurs AFTER I remove CharCustomizeFrameWithTooltipTemplate and I think I caused it with the above workaround, but I removed by commenting out frame:AddTooltipLine(text, HIGHLIGHT_FONT_COLOR):
