I'm from San d'Oria since 2003 and I got Sarutabaruta in november/december 2010 !!!
this was the second time that happened, I miss the first some years ago...
but now I have all OP..

p.s.
If I change nations, I'll lost every OP right? and if I return back to my first allegiance nations I'll find back my OP or I will have to re-obtain again?
