There was a character manager utility for Oblivion and I believe the Fallouts that would tell you what mods were included in a save when it was saved. Is there anything like that for Skyrim? I'd like to do some testing with some older characters, but I don't want my Helgen Reborn mod baked into the save, but I don't know how to tell if it was or not.

This would be a good idea.
PS:What's a Helgen Reborn?

Helgen Reborn: http://skyrim.nexusmods.com/mods/35841/?

I just tested TES V Savegame Manager, and it don't tell you anything about the save.

Wrye bash does this for all games it works with: Morrowind, Oblivion, Fallouts, Skyrim.

Just look at the saves tab and they are all listed in a side panel.

But that alone will not tell if a mod is baked into a save. Any active esp will be seen as a master for a save - that is unavoidable. Any clean save and they won't show again on the next save.

The baking into a save that is dangerous is mostly about scripts being baked in - that can be seen by enabling papyrus logging and then playing with the mod active - remove it - run the game again and see what is throwing errors.

[edit] there are other things one can edit I think that can be a danger to move, but what has caused most of the hullabaloo over the last year is the papyrus scripts being baked in and no assured way to clean them out once in.

[edit for clarity]

As long as I've been around I've never used bash, lol. That's your baby, right psy? I remember looking into it fir Oblivion but it looked like a steep learning curve and python and all that I just never got around to it, lol. I've honestly never really had a need to use it as I run a fairly gently modded game when I'm actually playing. But I'll see if I can look into it and get it running at some point. Thanks psy.

yeah i use bash to see what mods i used in a particular save. works well enough.
