Same here, kinda. I went down with 15% left in the final boss fight and the window to "rety from checkpoint" or "exit to vabbi" popped up right under where my mouse was when I was clicking to target the boss again... and as a result, I accidentally clicked "exit to vabbi" :( NOW, my story guide is stuck at the final "part" of the story inside the instance... and I'm outside the instance with no way to get to the green star to try and finish this, if I can even "pick it up" again from that point ... am I completely stuck? do I have to quit the chapter and start it all over again from the start???
