3rd time.../pcmd leave does not work in cross world parties

First of all, the previous 2 posts:
http://forum.square-enix.com/ffxiv/t...-does-not-work - working as intended
http://forum.square-enix.com/ffxiv/t...-does-not-work. - insufficient information


Second of all, just log in, start a cross world party, get people from another server and type /pcmd leave. Rather than leave you'll just get a party popup (social) window.

First one moved to "working as intended", second moved to "insufficient info"...
