I had $256$ reputation on MSE till yesterday. But today when I checked my account, it had decreased down to $216$. I did not post any question or answer in the past few days and there is no new upvote/downvote on any of my posts. The reputation change is also not visible in the reputation tab in my profile and the last reputation change was on July 20 as shown on the webpage. The reputation curve also modified cleverly and it does not show that I had 256 reputation ever even though I had.
Now you might be thinking that I never gained 256 reputation, but I did have it and I also had View close votes privilege. The Achievements tab mentions that I received View close votes privilege.
But now I no longer have that privilege due to this unknown loss of reputation.
Can someone please tell why my reputation changed mysteriously overnight even after no new post?
