Congratulations, You have found a bug! Don't worry, its not serious, most likely the Mud name chosen is spelled differently in one of the databases and just needs to be corrected. Please do your part by informing of us of this bug, simply send email to Icculus and be sure to mention you tried to access the statistics for the mud 'Mystical Mud', not much we can do without the mud name... We'll get the matter cleaned up as quickly as possible.
