has anyone else gotten this? i have miku v4x bundle with her jp and english banks, but all of a sudden when i opened piapro studio i see that miku chinese is available for me to use? she expires in 2999 so i'll have her for the rest of my life but i just kinda. got her for free i guess? she's perfectly functional and i'm definitely not mad about getting a free voicebank but just. why is she here i'm confused
