I don't think Ralph did any version numbers, so the date of the files would be the best alternative. As Ralph lists the date in the first post.
Last Update 12-Apr-2021
If you have the most recent version, then I'd recommend renaming the current aricsexpansion mod folder and extracting a new one from Ralph's archive.
The 3 autosaves issue was known about since a long time ago, but Aric's expansion wasn't updated to the last bugfix patch nor 1.0 (though a user recently provided a 1.0d version of Aric's mod).
The unassignable attribute points are a result of corrupt data, specifically all the max stat values are 0. The only way to fix that is to edit the max stat values to something reasonable like whatever the game says their racial maxes should be. I recommend googling a JSON online editor as I've found those to be quite helpful.
