Heroes and unflagging

Title says it all. At times when I flag my heroes then unflag them they seem to run the opposite way I am traveling. At other times they follow normally. Anyone know as to why the heroes seem to run away from you when you unflag them?

If there's a large distance between them and yourself when you unflag them, they have a tendency to run in the wrong direction.
The easiest way to solve it is to flag them closer to you, and unflag them once they're within range.
(If you play with them a little bit, you'll easily find the distance at which you can safely unflag them.)

Actually Kiva-chan, I've noticed that they will attempt to re-trace your steps if you've gone too far. You are right about flagging them close to you to get them to come. It always works.

It's just a bug, as far as I know, and an old one. You can work around it by flagging them closer rather than releasing the flag. If they still run the opposite direction, plant a flag within their aggro sphere, and use a flag chain to bring them back to you.

Ahh, you're right.
They seem to first trace their own steps back to your steps and then follow you.

So I guess another way to solve it is to walk from the place you flagged them? n.n;
