Offline Mode gone in 1.6.4?

[TheCorbin]

I keep FTB installed on my little brothers' PC, which is set up JUST for games, they enjoy playing with all the new mods especially with Direwolf pack. Unfortunately, I went through to update them to the newest version and it requires Internet Access. I keep them offline for a reason, and I don't want to have to reconnect their internet Every time they want to play FTB. Now 1.5.2 works fine offline, but 1.6.4 packs will not work. I logged in set it up, logged off, disconnected their wifi access, and then attempted to log back in, it will ask if i'd like to play offline, click yes, the button will stay highlighted for a few seconds, as if it's loading and then go right back to normal.

Is offline mode dead or is there a simple work around for this?

It appears to be broken at least for the 1.6.4 packs in the recent versions of the launcher. It has been reported. Look here for more info.
