Hello, my account on atcoder simply disappeared. I had an account called Settop. I was doing the ABC today and after the contest, I was browsing the standings page on the website. At some point, my account logged out, and I tried to log in again, but I couldn't: it said the password and username were wrong. So, I used the "Forgot my username" option. When I entered my account email, it sent a message saying there was no account for that email, but I'm sure that was the correct email; I even have a screenshot. Then, using the same email, I created another account and checked the standings to see if I could find anything about the account, but it was simply gone. I hope I can recover my account. Can someone help me please?
