Well, it was just first impressions, for me, but that is odd, as it doesn't line up with the changelogs. It may be setting pollution at a global level (as I previously played 4.5, though I created a new game). It has some new content in the some of the 4.5 scenes, so some of the work is there, just odd that certain parts, such as named saves (which, again, I don't use, so no loss there, for me) which were in subsequent change logs are no where to be found, so it makes me wonder what else from the new content might not trigger. I may look into a work around later, if it lacks more than named saves.
