Yeah, that's gone. Right now there are only 3 autofollow issues I'm aware of:

1) The most common one is what I said above. One character gets stuck on a rock and causes another character to be immobile. It's fixed by just going back and reautofollowing the leader.

2) One character ghosts and becomes immobile. It's fixed by going back re autofollowing the leader.

3) Flashpoint zones causes characters to break autofollow.

1 is the most common and can be a pain in the butt but if you round corners on turns and avoid barracades then its not a problem.
