I was about to answer a question, but realized that I missed an important point. So I deleted my answer to avoid getting downvotes.
After I edited my answer and pressed the save button my answer was gone. Usually it's greyed out and I can click undelete - not this time.
My workaround: I could browse back and copy&paste my answer. Then I wanted to post my answer again, but it said that my answer couldn't be posted because it's a duplicate of <question title>.
I had to add nonsense text to my answer so I could post it. Then I had to edit my answer again to remove the nonsense text.
Please solve this issue or tell me a better workflow.
