Seriously.. the companions are so stupid that it takes away the purpose to have one tagging along... they get stuck in thin air, can't move and im forced to either move them bit by bit by the "i need you to do something for me" or using the push shout, and that doesnt always work, i run down a small hill with a little path, then suddenly she stops runs back all the way around like 500 miles to get to me, so im forced to wait for like 20 minutes untill she arrives.... i really hope this is getting a fix pretty soon.. untill then ill run alone rambo mode

And this is why I've never liked companions. I have yet to see a game, not even Half Life 2 can get it right, where companions don't get in the way or their pathfinding is just horrible.
I have, and always will, stay away from companions unless forced upon me.
