I've just tried it again to make sure before posting this question but since one or two days at least, whenever I delete one of my answers, it becomes invisible to me.
I've just deleted this answer in SO. And It's now invisible.
I usually hang around in English Language and Usage. All the answers I've deleted over there (at least the ones I can remember) are gone. 10K users report that they can see these answers just fine.
Is this a deliberate or an unwanted feature?
