Hi, I found a bad bug: the scaling of the entities got wrong when you changed the type, now it is fixed!
//Changing server (see first page)
e.g. you can create a Convex for an entity: pXent_settype(entity,1,PH_CONVEX); and later delete it: pXent_settype(entity,0,0); and than create a new Sphere for the enitiy: pXent_settype(entity,1,PH_SPHERE);
