The only thing I ccan think of now is either omitting it or translating as if it were active (, "which you were awarded for " or "which [they] awarded you"). The "which" solution seems to be the better for me, since the achievement bubble has a title, point value and description, so it would retain the fluency and preserve the meaning.
