Back to back crashes is normally caused by our server re-booting for routine maintenance.
Invite delays is caused by T3DE's invite expiration h4c|< ... which allows you to hold onto and accept chat invites up to 15 minutes after receiving them. Which is a lot of fun to do ... people don't expect you to show up in their private chat room a full 15 minutes after they sent you a chat invite.
I think walkoff was left out on purpose, because it adds quite a bit of lag and unneeded processing to the client.
