See if you can make any sense out of this one:
Code:
8/22 20:29:10.594 Interface\FrameXML\WatchFrame.lua:328
8/22 20:29:10.594 An action was blocked in combat because of taint from Overhead - NamePlate690:SetScale()
8/22 20:29:10.594 Interface\AddOns\Overhead\Overhead.lua:161 Initialize()
8/22 20:29:10.594 Interface\AddOns\Overhead\Overhead.lua:224
Overhead is my nameplate addon, it has no fancy features, just skinning the nameplates.
This happened before 6.0 though.
