The only issue with that is that conventional monster spawns can't be turned on or off, unless you reboot the server, as unloading a file can bug it out. There's ways via scripts where a spawn can be toggled on/off, like I did with the Orc Spawns for the previous chronicles story, but that needs a bit of re-scripting. We'll look into it to see if it can be possible to add for future auctions.
