Custom face not displaying properly

[Vectif 377]

Hello!

Today I've been having an issue that I never had before. I been using a custom face for about 1-3 months and it always worked fine - both multiplayer, singleplayer, editor: and etc. Now, recently, and ever since yesterday; for some reason, it just appears blank - but only to myself. My friends and the other people who I play with can see the face perfectly fine, but it looks textureless to me; just plain white. What could be causing this and how do I fix it? I've tried re-making the texture, removing and readding - but it's still all the same?

Thanks very much in advance.
