I came across this question around an hour ago. Now, I thought I could give a decent answer, so I was working on an answer for the last 30 mins or so, because the user needed help with fixing a code snippet. Literally 2 minutes before I was done, the question closed. Now, all of my hard work was for nothing, and what makes matters worse, a user with 17k+ reputation just answered on the same closed question, and frankly speaking, I had a better answer than him.
If a question closes while a user is answering, shouldn't that user be allowed to finish their answer, even if they are not a "trusted user" yet? In other words, someone who starts an answer should be able to finish an answer, right? Should this be a feature request?
