Game Loaded with Edits Not Made by Me

Hi There,

I attempted to reach out to technical support but seem to keep getting directed to post on here. I logged in to my game today and noticed that the lot I had last played on was edited. I am the only one who plays this and has access to my account. One bedroom suddenly has a wall and gap between the door and the bedroom and most of the items that were in the room are gone. This also happened to one of the bathrooms on the lot, the bathroom was completely removed with the exception of the shower, it's just the shower in an enclosed room. I have tried restarting the game multiple times, restarting my PC, and no luck. I didn't save the game once I noticed this but every time I open it, it opens with the same edited rooms.

Any help is appreciated!
