you hunt over a dungeon / necropolis, walker see the mobs but there are over or under your char.
you must aktivate the "Z-Range" and give him a value auf 200.
then you didnīt see the "wrong" mobs.
this problem you have e.g. in cruma marschlands. the mobs that you see are mobs in cruma-tower
first or 2nd floor, if you activate "z-Range" (you find it under the checkbox "RealMap") you only see
the mobs from Marschland without the mobs over or under you.
