Is there an editing ‘grace period’ on answers after they have been posted?
I made a change to one of my pre-existing answers and then about two minutes later I was looking over the previous changes I had made. I rolled back to a previous answer expecting my already made edit and comment to stick around. They didn't, so the question I have is whether this is intended behaviour or a bug.
On a side note why have the tag possible-bug when bug is required? Or is that a user-submitted tag?
