The 'CLASS_BUTTONS' global, from which the texture coordinates for the class-icons is drawn, doesn't seem to exist anymore. I couldn't find anything about changes to the API, so it might be necessary to get the class-icons some other way.

Ok, I had another look around and found that you can replace CLASS_BUTTONS with CLASS_ICON_TCOORDS and it works flawlessly.

So change line 23 in modules\indicators.lua:

local coords = CLASS_BUTTONS[class]

to:

local coords = CLASS_ICON_TCOORDS[class]

and the issue is fixed. I got the info about the CLASS_ICON_TCOORDS global from http://wowprogramming.com/docs/api/UnitClass.

Fixed, thanks for reporting and the research :)
