you could remove the file that the command opens. Its not a lot of spawns to delete either if you know where to look. After you get it straightened out you can export all the xml spawners to an xml file to create your own spawn solution. Keep in mind these spawns are still not completely accurate with Broadsword shards. Peerless dungeons, wind, New Dungeon Revamp System, Mondains Legacy areas and Dungeons, and some overland spawns to name some. The Taverns spawn all the mobiles in a tight area not very immersive. This spawn is a good foundation, to get you in the ball park, most of the outdoor spawn are accurate to the spawn map utility and haven't changed much. FYI the mountain goat doesn't spawn at all and I don't believe there are enough small snakes (remember when a mild dose of poison was problematic when you were a newbie). Old OSI spawns from shard to shard differed a little, so you can only be completely accurate to a shard you use to play on; from your player bases' perspective.
Other considerations when spawning is how to drive players to areas of the map. On the Pacific Shard there was never any horses in Moonglow, but this spawns them there and just about everywhere there are farm animals, making it way to easy to find a new mount, also do farm animals really occur in the wild? Back to the mountain goat, a regular goat might be on a farm like a pig but a boar and mountain goat might be in the wild. I suggest trying to steer away from the cookie cutter spawns and making your shard a little more diverse and realistic.
