1) Go to https://pt.wikipedia.org/wiki/Special:Random?action=history&limit=3&uselang=en (I was redirected to https://pt.wikipedia.org/w/index.php?title=Tr%C3%AAs_Mist%C3%A9rios&action=history&limit=3&uselang=en when reporting this) 2) Notice there are 3 "undo" links (one for each revision) and two buttons labeled "Compare selected revisions". 3) Click on "Older 3": https://pt.wikipedia.org/w/index.php?title=Tr%C3%AAs_Mist%C3%A9rios&offset=20080730140720&limit=3&action=history&uselang=en 4) Click on "newer 3": https://pt.wikipedia.org/w/index.php?title=Tr%C3%AAs_Mist%C3%A9rios&dir=prev&offset=20080730140633&limit=3&action=history&uselang=en 5) Notice the 3 revisions are the same as in step 1, but the last "undo" link is missing 6) Go to https://pt.wikipedia.org/wiki/Special:Random?action=history&limit=2&uselang=en (this time, I got https://pt.wikipedia.org/w/index.php?title=Thunnus_albacares&action=history&limit=2&uselang=en ) 7) Click on "older 2" and then, in the new page, on "newer 2" 8) I'll get the same 2 revisions, but not only the last "undo" link will be missing, but also the last button "Compare selected revisions". I was able to reproduce the problem with every random page I got.
