[E17 Spoilers] Help with starting new sidequests

[Freya]

I downloaded E17 last night and just finished the new storyline stuff that was added. I went into Grand Hall to start Arclight's sidequest, but he isn't there. I bought all the pokemon from 7th street already a long time ago, and I even went back down there to see if I needed to go there to start it, but he's just not showing up. Am I missing something? 

 

Also, I've been going through the desert to unlock Mirage Tower. As I understand, you need to touch all the shiny things by each oasis to unlock the tower, and there's only one oasis out at a time. I'm pretty sure I got all of the oasis locations (there are like, 4 of them, right?), but they keep spawning in old places that I've already touched. I've gotten the oasis with the trainer who wants to challenge the gym thrice already, and I've gotten the rest of the locations at least 2 times each now. I keep checking where the tower is supposed to appear, but it's still just a bunch of rubble and empty pools of water. 

What am I doing wrong? :'D

 

EDIT: I touched a few more mirages and the tower showed up? I'm not entirely sure what I did differently lol. Still need help with starting Arclight's event though.

You need to defeat titania before the quest.

Is it possible you never finished the quest in it's entirety and thus got locked out of completing it?
