There some strange things happen with problems on Topcoder. Problem statement page is empty, but it can be seen in arena applet. And this happens for many problems. Some examples: [link](https://community.topcoder.com/stat?c=problem_statement&pm=14677&rd=16956) [link](https://community.topcoder.com/stat?c=problem_statement&pm=14673&rd=16956) [link](https://community.topcoder.com/stat?c=problem_statement&pm=14674&rd=16956) [link](https://community.topcoder.com/stat?c=problem_statement&pm=14675&rd=16956). Is this known issue?
