Lost citations on Scholar Checked my citation score and it turns out three citations (from 3 different articles) disappeared over the weekend. How can this be explained? I just hope it's some weird bug in the crawler. Anything i could do about it?

Since the Google algorithm is closed source, only Google can tell.

No. You could try to write Google but I don't know any case where this turned out to be succesful.
