I am sure that an upvote on a question is worth +5 reputation.
Now what I want to talk about here is the fact that earlier today, I gained +5 reputation from my question:
It did in fact give me +5 reputation and it gave me that no problem.
What I am confused about is that, only about a minute ago I suddenly got +8 reputation from the SAME question, though no upvotes or downvotes has happened to the question recently after the question's upvote.
It did give me a reputation boost to 2,458 but I don't know why the site gave me an additional 8 reputation just out of nowhere.
Now to look at my profile, earlier I got +5 from the question mentioned above:
And from the supposed +8 reputation, it has had no affect on the 'reputation gained since your last visit to the reputation tab' and it still sits at +5 reputation.
Why did this happen?
