DopamineNL: Although I personally feel this is my best cache (most original and interesting for others, which I feel are the most important aspects), sadly it's not coming back online...
After it came online no less than three (!) of the remaining invaders disappeared. After 12 years of hanging on in the Amsterdam streets they finally perished in their battle against the relentless and absolute culture-barren local city cleaners (the same ones who also destroyed my cache-invader, as is the inevitable faith of all street art..). RIP.
And with only a few invaders left there isn't much of a multi left to do. Feel free to find them on your own, I don't even mind if you log the archived cache when you do. Invader hunting is always fun!!
