Earlier today I downvoted an answer which has a cost of 1 reputation point. Later I retracted my downvote which caused the missing point to return.
In between I also capped out at 245 points (votes+3 accepted answers). After un-downvoting my reputation showed 246 points. I checked the reputation log which agreed that this is preposterous and I ran a re-calculation.
The top page counter was corrected but the profile reputation tab refuses to cooperate with this action.
