Stop spamming the log file with these warnings. The code does nothing to prevent them and they are happening all over the shop in msoy.

Was going to try and skip the call to ClientObserver.clientSessionDidEnd if it has not yet been started but there is not clear way to determine the state of a session. It is shared between three different maps in ClientManager and PresentsSession and movement between the states is too complicated, at least for tomorrow's release.
