I think Oasis is translating off the German version, because it would require less UI change--translation from Chinese to western text usually causes a significant length increase, so they wont fit in some *ons/boxes and require UI change.

Now, I won't know what version the German one is going off of and why that version instead of some other, but as far as Oasis goes, it's a matter of convenience to get it from German ver.

Maybe it would be more effective to complain there....
