hmm.. i just tested this

naruto 6p did not do extra standard after orochimaru gnw summon launched mystery

i believed naruto 6p standard only implies to ninja unit mystery & not to non-ninja unit mystery

however, if u still encounter this bug & it is reproducible event.. it is good if u can capture video of it

p/s: i will try testing other ninja like kakashi summer vs orochimaru gnw
