I did 6/10 Cinthia quests just fine (along with all the other quests but Sarah) but now when I click start quest this pops up: Fatal error: Call to undefined method Controller_Quests::cinthia() in /www/subeta.net/include/mvc/controllers/Controller_Quests.php on line 99

Edit: She's playing nice for now, I was able to complete the last 4 quests
