Are you using the latest server version? There used to be an issue where there could only be one timer with a given id running at a time, but that was fixed somewhat recently.

Do the mobs spawn naturally, or do they spawn as part of a quest? If the latter, you could probably do something like this:

$entid1 = quest::spawn2(npcid, 0, 0, x, y, z, h);
my $mob1 = $entity_list->GetMobID($entid1);
if ($mob1) {
  my $mobnpc1 = $mob1->CastToNPC();
  $mobnpc1->SetAppearance(2);
}

and do that for each mob that is spawned
