*spoilers* about ending?

[Jiji]

heya, yesterday i finish the game on normal mode, (kirito mode finished)..
i chose to save kureha, and i let zeliska protect me and die..at the end of cutscene, it's said i can rewind the time and save my friends. and i do that. here the point i got confused.. the quest mark on SBC fluegel, but when i'm go to there (in forbiden forest), there no trigger for event. some explaination would be nice

it basicly just rewinds you back a few story quests so you can get the other ending+true end.

It brings you back to the 'Enter the Flügel depths' part. Quest objectives are a bit vague and off at that point. Your next step would be do go to the last Flügel Bow waypoint , fight Brionac and continue from there.
