that was in TI near Spec Shop. When tried to move, appears end of soe effect and I was "teleported back" ( or how to describe that ). restart char didn't help, only relog. ( I use eu proxy ) that was only 1 time, when disappeared adena ( bug ) and I restarted to get adena.
guard with bow doesn't walk from his point, while guard with shield does it, but can't attack you till you won't stop running or reverse your moving (Same with mobs and summoning pets). I mean melee mobs etc have 1 second delay before attack and when you run, they are losing range and again trying to chase you.
