Having a new issue here. I started a new game from a vault save and did the whole sim settlements setup just so I could have a test save to play with the add on packs. Made my save. This morning I go in and enable your add on pack along with wasteland ventures, industrial city, jtbryants utilities, ruined homes and gardens, classic shacks, braes defenses, hunter-gather, and sim towers. Built a ton of plots in sanctuary and had to quit, so I made a save. I came back to it this evening and couldn't load the save. I disabled mods and when I disabled animal farm I was able to load the save. Tried it on some other saves that I had with animal farm installed and got the same results until I disabled it. This is on xb1 and i can send you the LO I use if you would like.
