Stutterbug in DE

I'm not sure if this is a new issue or if the latest patch fixes it, because i just finally made the switch to DE.

Whenever sending a unit to places, 50% they walk normally, and 50% they slowly stagger-stop-stagger-stop to the destination.

This has dangerous effects when luring boar, because the villager moves like a snail and if attacked in staggerstop mode gets the "bright idea" of turning around to fight the boar instead of carrying out simple, basic orders.

Also it effects every type of unit. I dont recall any such "single player lag" in HD.
