Can't find game commentaries

[KillerBeer01]

Sorry for disturbing you again, but I can't find audio files for game commentaries. In .drm they are marked like "vo\Commentary\hengsha1_capsule_hotel_visit2_a", but there seems to be no Commentary subfolder neither in the localized nor in the default part of the unpacked bigfile. Does it mean I use a less-than-latest build of Tools, or these hasn't been mapped yet?

Thanks.
