Looks like the Falcon is indeed 'lost in space'... when asked if he still had it, the last geocacher to have it in his possession said, "Im sorry, I don't anymore, I sent an email through the geocache site to the maker of that travel bug saying that it was lost in the move, sorry."
Hopefully, Solo will find a way to return the Millennium Falcon to carted space, but in the meantime, this TB is MIA.
