Hey, I've recently started using Noggit, it runs fine occasionally crashes, but that's a given.
It's the actual saving of the maps I'm having trouble with, I've tried lots of different things from all over the place but none have worked (Saving in Taliis after, offsetfix.exe etc.) and it's all leading to corruption in game. Missing textures, strange things like having the camera thrown to the top of the world leaving me looking down at my character all sorts of things. Another thing would be the water, I think that's pretty obvious to fix, export the watermap from the original ADT and import it to the new one?
Heres a picture of my current progress (A small edit, expanding the Twin Spires in Zangarmarsh) Taken in Noggit, because as I say I can't in-game.
