In the recent Codeforces Round 883 (Div. 3) in problem C I got accepted verdict on my solution during the contest. But now when I checked it, it gives me wrong answer on test 6 verdict. Why does that happen?

Someone successfully hacked the problem C during the hacking phase and the author added hacker's testcase values to a new testcase and system re-checked everyone's solution and gave new verdict.
Same brother. My C also system failed today.
