while we didnt have this issue with seb, we had it within HS for the doors and the keys in there. Since we dont have any corpses on the server, i found that it was the bit within the plugin::check_hasitem(); calling on corpse checking that was causing crashes.
Not sure regarding seb, since it doesnt appear to be handled through a player.pl (at least on my server) but it may be related?
Either way i cut out this bit of code from the serverfolder\plugins\check_hasitem.pl
Code:
#Check corpses
if ($body_count > 0) {
for ($i=1; $i<=$body_count; $i++) {
$body_id = $client->GetCorpseID($i);
for ($slot1=0; $slot1<=30; $slot1++) {
$itemid1 = $client->GetCorpseItemAt($body_id, $slot1);
if ($itemid1 == $itmchk) {
return 1;
}
}
for ($slot1=251; $slot1<=340; $slot1++) {
$itemid1 = $client->GetCorpseItemAt($body_id, $slot1);
if ($itemid1 == $itmchk) {
return 1;
}
}
}
}
and that seemed to do the trick - if your server leaves corpses not really sure from there, but seemd to fix up NL on the crashes related to doors an keys.
(basically any zone where a player.pl handled the key checks, 75% of the time when a player clicked a door/zoneline, it would crash the zone)
