IIRC the issue was related to the plugin::check_hasitem trying to check for corpses

#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;
        }
      }
    }
  }

By removing that (lines 91-10 it solved our issue.
