auto clear is tick'd but the missing files are not in saved. (some files are in saved so i dont think its that).

I've untick'd autoclear to see if makes a differance. But 2 nights since 4.2.6 loaded and 2 nights of missing files does seem a little odd when things were fine before that.

As you say it could be a bug. I'll count the downloads tonight and see what ive got tomorrow. ill keep you posted.
