Hello, Recently I received a mail from somebody who asked why I removed a reference to his book from a Wikimedia page. The problem is that I didn't. I indeed made a small correction to the Wikimedia page, however, I was not related to his book. After his email I returned to the page and checked its history. For some reason, according to the history, the version after my correction contains a number of spurious changes, including the removing of the book. I definitely did not made these changes. Moreover, if I "undo" my revisions the page does not return to its previous stage: these spurious changes are still there. Following is the link to page differences after I undid my revisions. http://en.wikipedia.org/w/index.php?title=Tomographic_reconstruction&action=historysubmit&diff=467150811&oldid=464272632 P.S. I set the severity to blocker because, in my view, all editing must be blocked before the issue is resolved. The situation when some changes are done in such a "mysterious" way is unacceptable.
You had made more than one edit in the page. If you are watching the diff of multiple edits it says: (One intermediate revision by one user not shown). If you click undo, it will only undo the latest version, not the diff what you see.
Yes, I made 2 changes: 13:39, 20 December 2011 13:40, 20 December 2011 That were undone (see the link in the original bug report). I really expect that after undoing the change the page will return to its original stage. I did hot happen because the page was altered by something/someone else and these changes do not appear on the history. In the first edit (13:39, 20 December 2011) I removed one line ONLY one line (a link to bronnikov-alrorithms.com. However, if you compare it to the previous version (22:54, 5 December 2011 Holdendp) you will see that there were more changes than this. These spurious changes remain even after I have undone my corrections. P.S. After filling this bug report I again attempted to edit the page, so please ignore the changes done after (09:02, 22 December 2011 Eli)
Sorry, my previous post contains too many typos. Please discard it. Following is a corrected version. In my attempt to edit the page, I actually made two corrections: 13:39, 20 December 2011 13:40, 20 December 2011 that were undone afterwards: 09:01, 22 December 2011 (Undid revision 466847261) 09:02, 22 December 2011 (Undid revision 467150799) Please see the link in the original bug report. I really expect that after undoing the change the page will return to its original state. However, it did hot happen because the page was altered by something/someone else and these changes did not appear on the "undo" list. In the first edit (13:39, 20 December 2011) I removed one line ONLY: a link to bronnikov-alrorithms.com. However, if you compare it to the previous version (22:54, 5 December 2011 Holdendp) you will see that there were more changes than this. These spurious changes remain even after I have undone my corrections. P.S.

marking high and tagging so that we can have platform eng discover the source of the problem
This is weird. I can't find any deleted edits (rev_deleted != 0 or archive table) for this page.

Here is a diff were only the link was removed: http://en.wikipedia.org/w/index.php?title=Tomographic_reconstruction&action=historysubmit&diff=466847194&oldid=273185931 Then you made another correction. And when you tried undoing your changes, you only undid the last correction.
