Odd. What I did was shutdown the server completely, executed:
Code:
delete from spawn2 where zone like '%poknowledge%';
delete from doors where zone like '%poknowledge%';
delete from grid where zoneid = 202;
delete from grid_entries where zoneid = 202;
delete from ground_spawns where zoneid = 202;
delete from object where zoneid = 202;
Then sourced in your SQL and restarted the server.
If you do #npcstats on each occurrence of the same duped spawns, are they both the same npcid and spawngroup (and in the 202nnn range ?).
