In https://fa.wikipedia.org/w/index.php?title=Topic:Ty5k3pyl2hsftxg1&topic_showPostId=ty91y6rcfhdwsznm there are two comments from me (Huji) which reference the page سقز (فرآورده گیاهی). The first comment was made when that page did not exist, and a red link was created accordingly. The second comment was made when that page was created through a page move, and the second link is blue, but the first one is still red and has class "new" (even though it actually does not link to an edit page.
I would venture a guess and say that this is a caching issue. Although purging the server cache on both pages did not fix either.
A screenshot is attached in case it fixes itself.
