It's the TB2X0RD not mime, and the user stop caching.
The same happens with a lot of TB's I move. And I'm sure were I drop them, cause usually I take a pic and post it the the TB page.
The similar happened to one of my TB2J12J, stolen on the 1st cache I've droped, now I've released the copy.
Conclusion: TB's can't be funny, and always attach a giant instruction kit.
