Something to possibly note, when talking to the dude running the private server, the game saves your character data every 30 seconds (probably the same time mobs repop) unless you zone, then it saves then, too. Since your XYZ coordinates will be included in that, it's possible illogical differences in distance between saves without utilizing teleports or other valid transportation methods can set flags, with being in impossible locations (other sides of impassible walls) a definite indicator. Basically going above flee speed on foot is pretty dumb, and even that can be sketchy for long durations.
