I have just bought a few DLC, do you think I can use them on my "old" save file? I know that a game started in for instance V1.7 will likely show some incompatibilities if you reload it in V1.8. But in my case I don't change the version, just the presence of DLC or not (which is not really new content, that's rather a flag to unlock things which were already present in the base game). I have started a game in V1.8.1 without DLC and I'ld like to continue still in V1.8.1 but with some of my DLC. Any experience?
