Missing Party Invite Acknowledgement Message

While fixing the party displaying problem, I noticed that after you invite someone and the player accepts/rejects, you no longer get any message displayed.
Before, it was "Offer was accepted/rejected" or some such. Investigation showed that the server does send the packet, but the client seemed to disregard it completely.

I pointed out that since the client->server party handling packets have been changed to their '2' version, perhaps there was also a server->client change... but I could not find the solution. But after yesterday's packet recording, I found it:

the previous version looks like this

so the only thing they did was to expand the flag's length - which will probably never be fully utilized.
