I was in the middle of writing a (in my opinion good and detailed) answer to a question on a Stack Exchange site I hadn't used before. But when I tried to save the answer, it turns out the question has been protected in the meanwhile. There isn't even any way to submit it for manual review or similar. I do have the +100 network bonus, but answering protected questions needs +10 on the specific site.
So, now I have an answer I spent 15 minutes researching & writing that I have to throw away, just because the question happened to hit HNQ and got protected as a result. That's a terrible user experience in my opinion.
Could the answer box somehow be made to accept answers that people start writing before protection gets applied?
