Bashicu already gave the solution as same as yours in [the talk page](see {KurohaKafka} (talk) 12:26, May 17, 2016 (UTC)).

After that, they received the another problem (I mean yours still has same bug) from [hyp/^,cos] (see {hyp/^,cos} (talk) 09:24, May 23, 2016 (UTC)) and they gave the second solution of it ('{BashicuHyudora}'s rule' in the post of {KurohaKafka} (talk) 09:44, October 20, 2016 (UTC). In the second solution of them is the change of Delta parameter which decides the added value into the copied bad parts.
