I modified the script slightly to make people not have max experience and therefore not level up every time they killed something.

sub EVENT_LEVEL_UP{
  if (!defined($qglobals{maxlevel}) || $ulevel>=$qglobals{maxlevel}) {
   quest::setglobal("maxlevel", $ulevel, 5, "F");
 }
 elsif (!defined($qglobals{kunarkflag}) && $ulevel==51){
  $client->Message(5,"Congratulations on reaching level 51! This is the maximum level for the current expansion. It is HIGHLY recommended that you set AA experience to 100 percent until you unlock Kunark. This will avoid any possible bugs resulting from you trying to level beyond 51.");
 }
 elsif (!defined($qglobals{powerflag}) && $ulevel==60){
  $client->Message(5,"Congratulations on reaching level 60! This is the maximum level for the current expansion. It is HIGHLY recommended that you set AA experience to 100 percent until you unlock The Planes of Power. This will avoid any possible bugs resulting from you trying to level beyond 60.");
 }
elsif (!defined($qglobals{kunarkflag}) && $ulevel>=52 && $ulevel<=60){
  quest::settimer("delevela", 1);
  $client->Message(5,"You can not yet go past level 51");
  }
elsif (!defined($qglobals{powerflag}) && $ulevel>=61){
  $client->Message(5,"You can not yet go past level 60");
  quest::settimer("delevelb", 1);
 }
 else{}
}
 sub EVENT_TIMER{
  if ($timer eq "delevela"){
   $client->SetEXP(180000000, 0, false);
   $client->SetLevel(51);
   quest::stoptimer("delevela");
  }
  elsif ($timer eq "delevelb"){
   $client->SetEXP(620000000, 0, false);
   $client->SetLevel(60);
   quest::stoptimer("delevelb");
  }
  else{}
}

I'm really having a hard time figuring out and sort of reason why this only works on some characters. I can confirm the people do not have the necessary flags.
