Today, my question at Can a substance have zero vapour pressure above absolute zero? had 3 upvotes and my reputation was 597 points. Later it had 4 upvotes and my reputation was 602 points. Later it had 5 upvotes and my reputation was 606 points and when I opened the reputation menu, I saw that it said I gained 10 points and lost 1 point and in total gained 9 points today. I think the loss of a point came from me downvoting an answer. Later, my question had 4 upvotes and my reputation was 601 but the menu still showed me as having earned 9 points today. A bit later before I posted this question. I saw that that question had 5 upvotes and my reputation was 606 points and the menu showed me as having earned 9 points today and the glitch seemed to have gone away.
Edit: Even later long after I posted this question, I saw that my reputation is 604 but it lists me as having earned only 5 points and as having recently lost 4 points so my reputation should be 602 now.

tab look? It'd be good to see from that log whether your interpretation of where points came from/went to is correct. $\endgroup$ – nitsua60 Sep 5 '18 at 1:22
