When standing half a screen away from a enemy I'll click on them then the character will "teleport or jump" to that spot on the screen. Happened for a good 30min even after log out and logging back in.
I am having the same issue not only am I jumping randomly across the screen the enemies are too. I can understand if they are teleporters but this is happening with several non teleporting enemies. I am playing as a Barbarian if this matters. I would not say it is half way across the screen it is more like an eighth to a quarter of a screen move.
