That is, assuming it may matter to someone.
For example, I deleted an old question of my mine with no answers; but when I viewed it under Recently Deleted Questions, it showed that it had one (displayed "1" in the answer box).
So I thought for a sec that I had missed it somehow, and that the rule regarding deleting answered questions had changed; but no, it didn't have any formal answers (i.e., answers not in comments).
Anyway, so I undeleted it and redeleted it to recheck the answer box, and it still populated it with "1" even though it was never answered, formally. But it goes back to "0" when undeleted (listed under the Questions tab).
I find little things like this from time to time, but I don't know if anyone else cares or already knows or where I should mention such a thing in any case. Perhaps here since "bug" is a tag.
