I've noticed today that with a few articles I've edited it appears when I check back that my edits haven't been implemented (but in fact they have). I've also seen a few other complaints on talk pages about edits and comments being "erased" though it seems that, in fact, this hasn't happened, it's just that the editor in question cannot see their own edits.
Is there some sort of glitch in the software when it comes to "updating" articles or to the ability of some accounts to "see" updated articles?
