make the radius of the waypoints bigger, the pilots or drivers must be able to see them as if it was u looking for them, nile can handle about 100 waypoint makers by memory (not 100 way point lists), if u just added some stuff like weapons or vehicles and now it wont load remove whatever it was u put in before it stoped loading, ive had a problem once of a map not loading after a certain type of weapon was placed on a certain building (it was the AA gun on a wooden tower) and as far as getting ai to attach to things use the ssn to ssn command and check the id numbers of whatever there going to to make sure their going to the right object. Also if u have change the name of the file make sure its not to long as that can make it not load aswell, as for the system dump well that comes free in the box from nova
