Character follow bug (Graphical)

Player A and Player B are in a party. B right-clicks on A and on B's screen his character runs to A and stops (as long as A is not moving). A starts moving. On B's screen, his character is standing right where he stopped, however, on A's screen, B is following him like the follow functions in many MMORPG games.

Reproduction:

1. Get two characters in a party.
2. Right-click one character with the other character.
3. Observe the characters screen that was right-clicked while that character runs around.
4. Observe the characters screen that did the right-clicking while the other character moves around.

It looks like either character A's client THINKS character B is following him but he is really not, or character B SHOULD be following character A, but is not properly following him.

It doesn't always have to be in party, sometimes it happens in towns, as well with random people.

Thanks for the info, personally only noticed it in a party (and by accident), but I assume it could happen anywhere that one player can click another.

I have noticed that when in party you can reproduce this bug every time.
all I or my wife has to do is left click on the other person, the other one sees them trail even though on there screen no movement happens.

hope this helps.
