Today while I am proceeding in ladder C from a2oj.com I faced "Statement is not available." in this problem 388A - Fox and Box Accumulation, I hope this will be fixed soon.
Thank you MikeMirzayanov for the great Codeforces and I hope for it to dominate the first place among competitive programming sites all the time.
There are a lot of problems contain "Statement not available." :/
I'm facing the same issue when I create mashup contest with polygon problems, html statement is not available, only the pdf one. :(
Thank you for notice. It seems fixed now.
