I asked a question named 'Indices' because I needed help with a question; I then submitted my question and some time ago someone else had asked the question with the title 'Indices' so instead of my question coming up, their question did but with my name??
I would understand if I asked the exact same question as someone else did, but I asked a completely different question just with the same name.
If have never had a question where this happened, but i once clicked on a question to answer it because it said zero replies, and when i clicked on it loads of replies were there and the date was from a long time ago. I tried it again several times, but it kept sending me to an old page. It had the same question title too.
Since then i've seen it happen on two questions that i have tried to answer.
