Apologies if this belongs in the 'mods' thread, I wasn't too sure.
After a million zillion hours of happy play I thought I'd try adding one of the mods that are out there. I selected what appeared to be a simple one that required only one text file (ItemCombos.txt) be placed in ~/GOG Games/Divinity_Original_Sin/game/Data/Public/Shared/Stats/. Not too much of a stretch, I thought.
Anyway, simple question; do I have to start a new game for this to work? because the new recipes don't work on an existing saved game.
