I build a module, run a game, save it, let people log on and interact, I DM, fun is had, a dungeon is explored and the town is a bit safer.
Except I want to add more areas, more adventures, more stuff for players to do than what I originally built. I can save a game but I can't modify the sav file in the toolset, and the idea of having to go into the toolset and literally do everything any of the players did and have players start new sounds... weird.
I'm pretty sure I'm making this more complicated than it really is. I've tried messing with Nwnpacker, there's persistencefacade and NWNx that seems to work with SQL that I'm totally unfamiliar with, I can't figure out how to modify a sav file so I can expand a game that's been played or if it's even possible to run a persistent world and add content after launching it beyond basically making a new module.
In the toolset code I found some scripts regarding area cloning, making, instancing ect but nothing about modifying tiles or doors. So I'm pretty sure it's not doable in game.
What's the magic that I'm missing here? How can I build off a small module and grow a world? What steps/ resources do I need to learn and understand do something like this?
