I reviewed 400 posts (or at least it said 400 in the all time column). I just looked back, and it now says 399 (the reason for this is most probably linked to the fact that there are two different numbers that are listed for the number of posts that I reviewed today):

Does this mean that something was deleted? Even if it does, since this was (or at least could have been) a product of my good reviewing, why would the count go down?

If that was not why the count went down, what is going on?
