i often saw a strange behavior/bug with mayadoll / animedoll and clothes. had to explain, i launched a thread long ago and even reported the bug to maya. uually this is what happens, you pose the character with cloths, and if you turn the body, or move any part (finger, hand, limb, torso, etc) the cloth will soon be distrored but if you move the same dial just sligthly more it goes again correctly and then continue moving the dial further it bugs again. intermitent/alternative bug on/off. had not seen it for a while (because i guess i inconsciently make anything to avoid it now) but if it reproduces again, i send a sample. maybe thi is the problem you experiment
