Looks like I've also reached the same quest roadblock as other players in SP. The trail has run cold at the emergency buoy near the rift to Heiron. I've read this thread and have a few questions. First I'd like to say that entering the Sol system and now the Altair galaxy is really where I felt the true Crossfire experience began. Nice work OP.
The clue at the emergency buoy is at best, "vague". Am I right to say I now must go to Omega 41 and find Utopia to continue the quest? I've searched my brain to try and figure out where I went wrong and can't find a reason. Oh well thank the stars for this forum.
