hmm how this could happened??? ..these mobs should have theirs wp's .. but somehow, someone changed movementType and set 0?
this should fix that problem
UPDATE creature SET MovementType=2, spawndist =0 WHERE guid IN (326,1012,3557,3574,3595,3596,4360,4361,4364,4377,4378,4522,5459,31772,37642,37647,37669,37671,37676,37677,37682,37691,37692,37693,37694,37695,37696,37697,37698,37699,37700,38347,39540,46818,51475,52070,52074,57656,58702,77361,77730,79750,84633,84716,85044,86177,86278,95560,115275,115276,127781,133611,135170,135210,135227,135228,135241,135253,135263,135265,135306,135338,135364,135445,135453,135473,135517,135530,135712,135729,135775,135805);
