On Friday, I added an answer to Copy installation files that Novell Application Launcher uses on Super User. I also upvoted the question.
Now when I check back today, there is no evidence of either the answer or the upvote.
What is up with that?
EDIT: In hindsight, I should have looked at my profile, but since the question looked exactly as I remembered it, the user name seemed the same, I just assumed the data had gone missing. I should have looked further, and seen what Diago saw, that the answer I had posted was still there, but there was a second instance of the question.
