It was lost and now it has been stolen.
It's what happened to us, when one of us misplaced DS's brand new build your own lightsaber at
Disneyland. He was only 4, and the thing was taller than he was. I had misgivings about getting it but it's *right here* as you exit Star Tours...so he and hubby made one, and it doesn't retract all the way and there's no handy belt loop...
And 2 days later, he was carrying it, he had it in pictures at Princess Fantasy Faire...then we stopped at the benches on the way into ToonTown (a minute away), reorganized, and then as DS was in line to see Goofy, we realized the saber was gone (probably 5 minutes had gone by). None of us remembers what happened with the saber...we don't know if DS set it down and left it, or if he handed it to us b/c it was so heavy (as had happened several times already) and then the adult he handed it to set it down...we have NO memory whatsoever of that lightsaber after PFF...
But it was gone. And it was never turned into lost and found, though a *different* build your own was turned into Star Tours and was sitting near the CM waiting for the rightful owner to get it...
So we lost it, and then someone stole it. Somewhere out there, a child, teen, or adult has a lightsaber they did not pay for, and was not theirs...and they stole it.
