 We know how to make 1 mob remember a player by saving their name in a variable or table, but what if we wanted that information available to other mobs or even objects and area scripts?

 Ok, it LOOKS like it's working, but how do we know if the info got saved?

 Final notes: savetbl and loadtbl will always save/load in area specific directory (angel's heaven dir in this case) according to HOME area, not current area.
