Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Terrain Edition is locked

Hi all.

I'm exploring The Divinity Engine and got one problem.

I can create mod and run it into the game.
But after that I can't edit terrain of any location.
And I got the same behaviour if I try to edit Main module terrain.


My workflow:

1) create terrain
2) add AiSeed, add StartPoint, add Player
3) Generate AI grid
4) Story - Generate Definitions and Build
5) Set up properties of a module (start location and number of players)

My question is: Why I can't edit the terrain in location?
I must set some options in the editor for edit terrain or I can't do this after some steps in my workflow?
