Mass amount of users on grid effects presence and hideing your self from people doesnt work too well cause it forces server to hide the person but doesnt hide them cause website shows them as online alot of the friendlist problems came out when the hide ability from other people was implamented and since then the bug has been overlooked and became very serious as of resently presence isnt effected too much on beta grid though since there is a low amount of users.
in turn over 10K of users cause friendslist to malfuction
over 20K of users friendlist prence doesnt work and overrides it to show users as hidden
over 30K of users doesnt show anyone at all
hide presence is the cause of the friendlist issue and needs to be reassesed
