20171231_es_second_quote_201803_20180316.csv file is missing in 20171231_quote.zip. It caused FrontMonth() to return ES contract with expiry on 2018/06/15. However, it should return the contract with expiry on 2018/03/16. The issue was reported in this ticket. And I also created a related GH issue. Same for minute and tick resolution.
