Yes, you can certainly use my DB data if you want, the only thing is the current version is still quite buggy (as I'm sure you already know

) I'm still working on fixing it, and will probably release another version when the merchant lockup bug is fixed in the 2.4 beta.
Also I'll eventually release my NPC data parser/converter utility with the source code for it, which will make it a lot easier for other people to make their own spawn lists (it takes a single .txt file with all the NPC info in it, and outputs the npc_type,spawn2,etc tables in MySQL format). I still need to add a few features to it though before I do this (such as factions being stored in the NPC data, currently they're just autogenerated based on race)
