Okay, so I just tried to farm some guy on Quantum and I got the error message "There is a war already raging against this realm, also from your location. You do not want to step into the middle of an existing fray." Now, this messages is supposed to come up when someone with the same IP as you has attacked the guy (recently), but this hasn't happened. One other person plays from my IP (my girlfiend), but we have the IP exemption, and also, she has no strike and hasn't tried to farm *anyone* this wave, much less this guy, so clearly I should not be getting this message.
The guy who I got the message when I attacked was ID 20353 and my Id is 2241.
