Exactly the same happened to me today !!!!! :-(
It was my second geocaching experience... just close to my first find.
I decided to leave my brand new travel bug (a gift from a geocaching friend) in this second cache.
I kept the travel bug marked "Copy" and left the other one, brand new in its original small plastic bag.
When I came home, the trackable item page requires an activation code that I was not aware of!!! (I am new to geocaching!!!). So I believe the activation code is in the small bag with the cache, in a small piece of paper with the geocaching logo. I thought it was just a logo paper, advertising only.
The cache is like 90 km north of our house...no chance we are going again any soon. And worst, we are leaving this country (Qatar) in a few weeks.
I will write an email to contact@Groundspeak.com and see if they can get my activation code replaced.... This is my first travel bug placed, and I really want to be able to track it!
