That's a weird title for a bug report: Answered question with positive scored answer appearing in unanswered question list.
This question: Wallet initialization failed: basic_string::resize on Monero Stack Exchange beta was recently merged with another thread. Before the merge it had no answers and was listed under unanswered questions.
Now, after the merge, it has one answer with a positive score (+3) and should not be listed there anymore. However, there seems to be a glitch and the question is still listed as unanswered.
The merge happened 3 days ago, so it is definetely no caching problem.
Edit, as per comments, should be: status-reproduced
