Mapnote on main UI screen

[Jinglehopper]

I have a green mapnote style blip that somehow appeared in the last three weeks and I don't know how to remove it. When I mouseover the blip, I get this error:

[string \"<unnamed>:OnEnter\"]:4: attempt to index field `?' (a nil value)\

Because the frame is unnamed, I am unable to select it and remove it with DFM. I'm at a loss, short of disabling every addon I have installed (over 100) one by one, I don't know how to isolate this problem and remove it. I was wondering if anyone has had a similar problem and could point me in the right direction. Thanks.


edit: spelling
