It really isn't that odd to lose a cel when you 
have a ton of them in your house.  I lost a 
marmalade boy cel I loved very much and have 
never found it :(  I imagine it was probably 
sent by accident with some other cels when I 
sold some cels off a while ago but I don't know 
to who so there is nothing I can do.  Stuff like 
that happens all the times.  Soemtimes I think I 
lost cels and then find them months later.  It 
sucks when it happens but is not really 
strange,  believe me the dealer is probably more 
upset than anyone!
