Every time I try to start a Drunk Carl Quest, I get a white page with this written on it;

Fatal error: Call to undefined method Controller_Quests::carl() in /www/subeta.net/include/mvc/controllers/Controller_Quests.php on line 99

I'm not sure what causes it, but I've had that happen, too. If you check your URL, it'll show /carl/carl/start/ instead of just /carl/start/. Remove a slash and his name and it should be fixed. it might happen again, but altering the URL is how I get around it.
