Hakliva: This cache has been with me a LONG time. During its life, it has stumped SEVERAL people leaving them with a blue sad face. After I get those logs, I would usually run over and verify it's still there. I stopped doing that when my cache hide count rose significantly and my work area shifted.
Well... its been a year of DNF logs, I finally popped by, and I very well could be blind, and it could still be there, but I did not find it, and I think it is time to let go.
