I realize one must participate on Stack Exchange for a certain length of time before becoming a "trusted member" and having upvotes show immediately on answers. I passed the "trusted membership" mark months ago. Since then, I get notifications of upvotes and they show in the space beside the answer, i.e. the 0 turns into a 1 or 2, depending on the score I am given. Recently, however, on one of my answers the 0 does not change even though I got notifications of points earned.
According to notifications my answer for "Is it correct to say “the Lego got broken apart”?" earned +23 in the last 7 days. It does not show; i.e. the visible score still stands at 0.
What am I missing? Why don't my rep points show?
