The current version of PRP is 1.1!
Model euaf.hrc looks the same way in a vanilla install of FF7.
I guess she was never meant to have a face.
Usually when a model is missing the face texture, there's a white box where the eyes and mouth should go.
I don't see any change from the original in the models: bxjb.hrc, byba.hrc, bybf.hrc, bycd.hrc, dhhf.hrc, ebjf.hrc, ecae.hrc, eoce.hrc, fgec.hrc, fgfb.hrc, grcc.hrc, guhc.hrc, guib.hrc, gvae.hrc, hagb.hrc.
Plus, there are quite a few updated models not in that list.
