Why is my object jumping to 0,0,0 coordinates?

Object seems to work fine unless I use the following function to return an object. Then it throws my object at 0,0,0 position? After searching for a possible solution I found that people seem to have a similar problem with animated objects. My object is animated but like I said, it only jumps to 0,0,0 when I use this function.

    GameObject _getTarget()
         {
         if (_team==1){_enemyAll=dynamicMesh._teamAall;}
         if (_team==2){_enemyAll=dynamicMesh._teamBall;}
         if (_team==3){_enemyAll=dynamicMesh._teamCall;}
         if (_team==4){_enemyAll=dynamicMesh._teamDall;}    
             
             GameObject enemy;
             enemy=_enemyAll[0];
             {
                 float thisDist;
                 float enemyDist;
                 enemy=_enemyAll[_enemyAll.Count-1];
                 enemyDist = Vector3.Distance (transform.position,enemy.transform.position);
                 for(int i = 0; i < _enemyAll.Count; i++)
                 {
                     thisDist = Vector3.Distance (transform.position,_enemyAll[i].transform.position);
                     if (thisDist<enemyDist)
                     {enemy=_enemyAll[i];enemyDist = Vector3.Distance (transform.position,enemy.transform.position);}
                     
                 }
             }
     
             return enemy;
         }
