"Out of avatars" error after refreshing the lobby repeatedly

    avatar = Player._get_avatar(self.used_avatars, pref=player.avatar)
  File "/home/thomas/Documents/src/Codenames/player.py", line 40, in _get_avatar
    raise ValueError('Out of avatars')
ValueError: Out of avatars

I think this happens because, every time the page is refreshed, all players tied to the device are assigned a new avatar by the server but don't end up using it on the client.

yeah this is a really weird issue. i think it has to do with the cookie identifying a client gets lost, and then there end up being dangling clients in the lobby taking up avatars.
