When I first unlocked the lv 3 difficulty after much luck, I did a test run but was failing miserably I wanted to try a full mystic build but because the game quits completely I lost all progress back to lv 0-1.
Later I regained it and made a couple lv 3 files, but it seems to never stick around after leaving the game. I even tried running a build up to the boss and quiting there but it won't let me keep the option for lv 3.
Idk why my luck is so terrible though, as the first event I get in a map almost always determines the rest of them. Worst of all is I get the same results each time I try them. Which is nice for a win streak of events, but it's scary for lost streaks.
