Explanation
Hand-typed message (CRLF) sent through the bot's live MD5(name+title) encryption between draws 429 and 430 of run 854,622,578, with no draw used. The point is a Google-Maps-style pick 5.8 m from the centre of the Agriculture Pavilion, Three Revolutions Exhibition, Pyongyang. Same place/time/code layout as 11dxb7 and 1iwqql; the time is 4 weeks ahead and matches no bot or public event. AO34 is unexplained
