Sims 4 Duplicate world and Lots infinite loading

So I was able to figure a few things out. 90% of my save folder is apparently corrupt. The earliest save I have in the folder is March 17th, and the latest was around April 28th when I stopped playing for a few months. All of the files but the March 17th file refuse to load many lots, they all just infinite load. I was going to see if I had saved anything from that time, family or lot, and I did find I had saved a version of the family sometime around April. The file is corrupt, clicking on it all of the Sims profiles state "This file is corrupt, remove it?" Deleted it so its not in the gallery anymore.

Shortly after the March 17th file, I was playing 2 Vampires and one became infected with the Plant Mother virus, I began doing the cure storyline but got bored and I did a recovery save before I started the story and began playing from there. I believe at that point the files all became corrupted. I remember saving on the world map, which I remember also reading is a bad decision as it can lead to file corruption, unsure if thats true or not, but well here we are. 

TL:DR, The March 17th file works perfectly, will test it out a bit more when I have the time to sit down and play, I want to make sure its not just a odd fluke and then suddenly other lots I haven't tried stop working. I am a tad concerned that the gallery versions of the Sim family and their lot may be corrupt but its not telling them they are, unsure how that would carry over.

I can still send you the folder when I have the time, its 5.70gb, but I might cut that down to just the working file and the most recenty not working file.
