I recently wanted to revisit my old, old saved games, but I had to realize that, unfortunately, a significant majority of the mods and tools I used are no longer available in the steam workshop (and thus the autosubscriber can't download them).

To make matters worse, most of the props are also gone, and without them the save file won't even load.

Is there a third party app that can help me - for lack of a better term, "re-vanilla" my save games?
