please start from this page for explore, not from difficulty selection. players can click bottom left corner if they needed to change difficulty. as your program already save last difficulty, it should be fine not selecting difficulty everytime.
sequence is that : start explore (difficulty will be locked) > count down 0/4 same as usual >… > mythic boss
i dont mind you increase 0.1s at loading screen for compensatation, but it will save my finger by not clicking it everytime.
