This is rather strange. If I go to https://wiki.lesswrong.com/wiki/Intentional_Insights, I see Gleb's last version. If I go to https://wiki.lesswrong.com/index.php?title=Intentional_Insights, I see gjm's version. However, clicking on the history tab of the latter page lists no edits since Gleb's of 19 November.
On the "Delete" page, the history at https://wiki.lesswrong.com/index.php?title=Delete&action=history shows a third attempt by VoiceofRa at 18:49 on 30 November 2015 (timezone unspecified but probably UDT) to delete the InIn material.
There seems to be some sort of inconsistency in the wiki. VoiceofRa's misuse of redirection does not help.
Try doing control-f5 to force a full reload of the page. Until I did that, I found that I saw "my" version when logged in and Gleb's version when logged out. I think I saw weird behaviour in the histories too, but I forget exactly what.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
