Anybody playing this will know that theres problems with this game when inviting friends, everyone seems to get a message either unable to join or session no longer available. I found a temp fix which worked for us last night which will help temp until EA get this sorted. 1.One person being the host send invites to other people they want to join party.(leave the game running still in hosting) 2.Other people DO NOT accept the invite just leave the message on your system 3.Other people sign out of playstation network and quit the game 4.Other people re-load the game while still logged out of PSN 5.Log back in to PSN with game running the accept the invite It does work I have tried, I hope this helps until they get it sorted although I don't know why EA have changed this the party invite works perfectly well on other editions and having to leave game to go to your friends list is a pain. Mod war 1 and WAW you can just add them from in game rather than the PS interface. If it not broke...... is the story.
hopefully will be good to go.
