Rival List Random or not?

[Dr BoneCrusher]

Hate to complain but, rival list refreshing really erks me. I robbed this guy for 270k he had over 750k unbanked about 2hours ago. Now no matter how many times I hit refresh I can't find him. I see the same people over and over again then every 15 times or so I get some new people. is refreshing truly random or an I doing something wrong?

Well if he dose not have any other properties left to rob and he has been attacked more than 10 time (2 hr reset) I do not believe he will show up on your rivals list.
