Party GUI
 

When a player goes offline, his/her portrait is still displayed until you leave the party yourself, or re-invite that player. Nothing major, but slightly annoying, fix pl0x. :D

Fixed.

There's also a problem with the party leader system. When you kick someone from the party it says 'so and so has left the party' but they still appear as in the party... Should have a message of 'x has been kicked/removed' from the party and they should certainly not be displayed.

And party leader shouldn't be able to 'kick' himself...

There's no such thing as "party leader" in GK's party system as far as I know, the GUI system just made it look that way. "kicking yourself" is the same thing as leaving the party.

There are party leaders but they are poorly implemented.

How are they determined right now? Shouldn't they technically be whoever originally formed the party?

That's how right now, but there needs to be functionality so if a party leader leaves the party/logs off it gives the party to someone else in the party. Currently there is no function for that, also parties aren't destroyed if no one is in the party.
