I found this really weird bug just now... In here the question link is redirected to wrong question when you are not logged-in, but when you log in again everything seems fine...
take a look here...
Steps:-
- Visit this page in logged off condition
- Find a question Q:Review queue in the topbar makes a man sad when he can't act upon it [duplicate]
- Click on that question.. It redirects to this question
- Now loggin again.. you are then redirected to correct question.
