I've brought friends onto the server, and they have all experienced the same issue. They all share the same veteran rank. When they try to use the command /ma j ma1 they are met with a "You don't have access to this command." line. DasEmpty was able to join mob arena before, but has been unable to for two days. MormonsinSpace, aj5x5 also experience the problem, but have been unable to join mob arena since they joined, never before.
