I find that this Superuser question,
Concatenate pdfs without losing bookmarks
- shows last-modified by "
John T" when the question is listed
(for example recently activepdftagged questions), - while, the question page itself says last-modified by "
EvilChookie".
The revision page for the question does not show "John T" anywhere.
Is this a bug?
I don't understand how my cache could do something like that.
