I just restarted the game, playing with a party consisting of one lone rogue. Pretty fun so far! My problem is that I've just returned to the starting village, now that I joined all of the major guilds. The first fighter quest, "Kill Mon the Scuz", isn't going so well because I can't find the bastard. He always used to spawn near the Hidden Circle gang after I talked with them, but he's nowhere to be found now

I found him on the road to Lake Nymph.
