I'm able to edit my deleted question but I cannot look at it nor undelete it. After pressing the Save my Edits button I'm redirected to a 404 page, but by reloading the edit page I'm able to see my the new revision.
Here's the edit link, that I can use to edit it. How did I get that edit link? Simple: I deleted the question and pressed the edit link thinking that I could undelete it later. (Which I can't… well, maybe I could using the correct link.)
