I am stuck. I have completed all the quests in Unicorn Way, Triton Ave, Cyclops Lane, Firecat Alley, and Crab Alley. I only had quests left in Colossus Blvd and The Oasis and couldn't get into either, so I got a friend to go into Colossus and transported in there. I was able to complete a few of my existing quests and picked up a quest in Nightside. I can't get into there either.
When I go to Merle, he says something about "We still haven't heard from some of our people out there...", but from what I've read after beating the bosses of Triton, Cyclops, and Firecat, he is supposed to be giving me a quest in Colossus.
