Forum:Companion keeps running off!

After dismissing Lily recently, I've noticed that she now spawns with me whenever I use fast travel.

I dismissed her to Lucky 38 and then Jacobstown - but at each arrival after using fast travel she will appear next to me.

Then she will immediately run off, and on the way start killing bugs etc. which will interrupt my screen with the 'death-cam'.

I've tried spawning Lily next to me and telling her to follow me again, but immediately after she will run off again.

I think it may be caused because I re-spawned Lily once using console. And I've found I have 2 seperate Lily's when I use the 'moveto player' command. One who I can talk to normally, but will then run off. And the other Lily always has the 'companion menu' pop up even though they haven't been asked to follow.

I've already tried lots of console commands (disable, enable, kill etc.) but nothing seems to work.

Is there anyway to force remove them as a companion or get her to stay and stop running around?
