pl.isBuddy on clientside
 

This pl.isbuddy functionality (for the playerlist) seems spotty. Seems to work if I choose not to use the serverside saving playerlist option, and seems to work temporarily if I manually add the player to my buddylist on the client (but stops functioning after I log off).

Is there some other function or variable that has the same functionality but is more reliable / works with the serverside storage of playerlist?
