Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Game Master Any news on adding mods to an excisting GM save?

There are some news!

We added support for adding addons to existing gm savegame. You can find appropriate button in Load menu.

Thanks Seter, awesome news!
From the patch notes:

And this may even allow for exporting and importing characters from/into an excistng save using the method described on the previous page.

As i said previously - direct manipulation with a files are dangerous and we not guarantee things to work after that - but yes. Now it will be a bit easier.
