Hello my fellow adventurers. I'm here to warn you that Aegon Statz has made an error in assigning Welterweights the activity of defeating a Midnighter in Chelsea Court. Apparently you can only face these creatures after accepting a main storyline quest. I'm not sure if it is even possible to get to Welterweight without already having finished this quest. We only have one resident who is within the Welterweight category and she's in Zafaria for cripes' sake. Good going Aegon! For more information you can visit the official Wizard101 forum for their announcement regarding this issue.
