UV background missing

Micheus, sir, thanks for the quick response.
Tried dropping but with no luck.
Just as a last ditch method I re created the texture and it worked. Moved to another face with the same material and that seemed ok. Tried the same on another face/material and re created that..... so far so good.
Looks like I just have to recreate each of the textures just on a single face and the others are sorted.
Will post updates!
