Allow joins switch/password issue

[Name]

It seems to work fine for players at large, but it appears at some point players in your guild can still join a party with you. I've had guild players create a party with me while I had Allow Joins on AND off with a password enabled.

It looks as though players are only able to join once after I logon because after leaving the party and checking my join settings I don't seem to get anymore players joining until I refresh my game again.
