I started to notice that areas in the game no longer have all the skulls and points of interest showing up on the maps.  I thought that maybe I messed something up and tried restring everything back to default with no luck fixing the issue and have even tried uninstalling and reinstalling the addon to see if this fixed the issue no luck with either.  Is anyone else having similar issues?  The zones I have noticed so far are The Uldum and Vale assaults as well as Draenor when I am flying around mount farming.   

Same here, on one toon the icons are not on map. in Settings the function "Mapoverlay" is also gone.
on other toons it is working as intended

So... Somehow the setting 'MapOverlay' was disabled in the main add-on setting.
i am stupid
problem solved

@faelinis hm, I think that I should improve the visibility of that. It should probably be reflected in the icon somehow, at least.

It is these settings, Map overlay can be disabled by blizzard i think (add-on interfering?) (sorry for bad english)

@TemperTemperton's issue appears to be the same thing.

Personally, I'm not seeing it happen, so I'd like more information. Here's a Westfall equivalent to @TemperTemperton's screenshot:

Now, what I want to ask:

• Is SilverDragon otherwise working? (E.g. are alerts appearing when you see a rare?)
• Do you see the SilverDragon icon in the top-right of the map frame?
• If you do, is it in color or grayed out?
• If you do, and you mouse over it, do you see a list of mobs or just it saying "None"?
