After clearing some old non-working replays I had 2 remaining that were still good after the update and 1 from yesterday (the 14th) for a total of 3. Now, the 3rd (and latest) replay seems to have vanished.
*edit* Hmm.. I did some testing and it looks like when you click 'Delete' on a replay in your profile it deletes it immediately. It's very possible I accidently clicked it somehow and deleted it myself so, I'd like to request a yes/no confirmation when you delete replays through your profile... :)
