my quest button won't show up??

hi! cherry81 here. after doing chapter 2 in the swamp,, the quest button vanished??? please help meee :'((

 

Are you asking about the quest button shortcut you get by default? Just do Menu → Settings → Shortcuts, then tap any shortcut slot, followed with Menu → Quests
Or just read the quest in Menu → Character → Quests

If you're asking about the quest itself, then here's a rundown on how main quest (MQ) should continue.
If you finished beating Mauez for your MQ(The Moon Wizard), there should be an exclamation where Tecaca was(Nehalo Swamp), that's where this quest should end.
The quest after(The Follower and Hater) should also start from the same place, then you have to go to Witeka Scorched Plains (dialogue w/ Tolala), beat Ganglef in Scaro Town, and beat Demon's Gate in Saham Crater

 

omg thank you so muuuch
