Yet another Party Bug Report

Trying to join a 5/6 party CONSTANTLY sends the message 'party is full' when it clearly isn't! Really frustrating when trying to team up with 5 friends. Also, since people aren't very bright, maybe disable the ability to join a party that has already started a 'Trial' since the leader doesn't know to make it 'Private' once they start the trial. Clears all the party clutter from the Q that way so your not bouncing in a party only to find out you can't join/travel to the started instance, and then having to leave and start looking for another. Just a QoL thought.
