We are sorry for not having controlled the situation about the streamed editorial and also for the broadcast message about an unethical behaviour of someone from community: here is [explanatory comment](https://codeforces.net/blog/entry/65664?#comment-496450) to the message. When we tried to move the casino problem one position below, something went wrong leading to it being moved one position above (however, [user:Radewoosh,2019-03-04] didn't seem to feel that something was wrong, congratulations!).↵

Nevertheless, we hope that you liked the problems, and those of you who decided to do something else after you knew that the round was made unrated can solve the problems when convenient (if they wish).↵
