There is something I found in the mob lazy ai code.
CODE
if( map[md->bl.m].users>0 ){
// Since PC is in the same map, somewhat better negligent processing is carried out.
// It sometimes moves.
if(rand()%1000<MOB_LAZYMOVEPERC(md))
mob_randomwalk(md,tick);
else if(rand()%1000<MOB_LAZYSKILLPERC) //Chance to do a mob's idle skill.
mobskill_use(md, tick, -1);
// MOB which is not not the summons MOB but BOSS, either sometimes reboils.
// People don't want this, it seems custom, noone can prove it....
// else if( rand()%1000<MOB_LAZYWARPPERC
// && (md->spawn && !md->spawn->x && !md->spawn->y)
// && !md->target_id && !(mode&MD_BOSS))
// unit_warp(&md->bl,-1,-1,-1,0);
}else{
// Since PC is not even in the same map, suitable processing is carried out even if it takes.
// MOB which is not BOSS which is not Summons MOB, either -- a case -- sometimes -- leaping
if( rand()%1000<MOB_LAZYWARPPERC
&& (md->spawn && !md->spawn->x && !md->spawn->y)
&& !(mode&MD_BOSS))
unit_warp(&md->bl,-1,-1,-1,0);
}
this says that, when there are no players on the map, every mob will try to teleport every second at a 2% chance. A practical experiment showed that from 100 porings, 10 teleported in less then a minute. This basically means that it's impossible to "clean up" a map because once you leave, any path you clear will get filled almost instantly. I strongly suggest tracing the history of this change, and verifying if it's official.
