Need help for building a "SIN" language pack

[Nagahaku]

Hi, I'm trying to make a simplified chinese language pack with the "SIN" slot, and got a big trouble on that...
It seems clear that "SIN" is for another type of chinese language, because it's matching with "CHI" fonts by default.
I have put the "SIN" strings, UI, fonts into proper folders, and switch language to "SIN" by changing "use" value, run the game, then I found that only the strings and UI for "SIN" are correctly loaded, yet the fonts are still using "CHI", so perhaps the "SIN" slot is bugged...
Then i tried another way, switch language to "SIN" with PlugY, and everthing is the same as before, only strings and UI are matched with "SIN", fonts are still "CHI"
Finnally I tried to use some other language slots instead of "SIN", I tried Japanese first, put the strings, UI, fonts into JPN Folder, and got a success.
So i'm almost sure that there 's some kind of bug with "SIN" slot, and maybe it's within d2lang.dll or some other dlls... is there anyway to fix that by code editing?
