My worlds completely reset

Hi!

So I purchased the Adventure Awaits and the Enchanted Nature packs a few days ago. When I went on to resume my game, all of the worlds reset, townies included. All of my builds, Renos, etc. are just gone and back to when you start a new game. The last household I was playing was still there, in the house I built for that, but everything else completely reset. All of my mods/ cc show up normally if that's in question. Anyone else encounter this issue and or know if I can fix it?
