Where is created the variable CageHuman? If is global you need to destroy the previos creation of the object before you create . In command replace

If (IsValidObject(CageHuman)) DestroyObject (CageHuman); // do it for all before create

CageHuman = CreateObject(971, Float+4.0,Float:y+4.0,Float:z+0.0, 0.0, 0.0, 0.0);
