Well, phooey. I originally tried adding button.cd:Hide() to auraIcon in oUF_Ammo. That's the name of the function that overloaded PostCreateAuraIcon.

Here is what I tried for that:

local function auraIcon(self, button, icons, index, debuff)
	button.cd:SetReverse()
	button.icon:SetTexCoord(.07, .93, .07, .93) --zoom icon
	button.overlay:SetTexture(bordertexture)
	button.overlay:SetTexCoord(0,1,0,1)
	button.overlay.Hide = noHide
	button.cd:Hide()
end

All I did was add that last line. Thanks for the help!
