I have spotted a strange behaviour and I think it is a bug. I have found this question:
I have made it not clickable, since it goes to the wrong question anyway. It was on Stack Overflow, and has been migrated to Database Administrators. It redirects to the following question, which is plainly the wrong one (different text, wrong user):
The question does appear to exist if the terrible title is searched for (at the time of writing it is at the top in each case):
I am not worried about the question itself - I have no idea if it is good or bad since it is not possible to view it. However, the dodgy redirect probably needs looking into.
