So I'm pretty far in the game and I've done a lot of stuff for fun. I expanded my farm area a lot, put a different fence up to mark out my space, built myself a freakin' huge mansion, and when I last left off I was making a smaller "guest house" (not that anyone would be using it.) Today I came back to my game and a big portion of my guest house and some of the fencing around it were ruined. A patch of my farmland had randomly reverted to its original state, ruining a big chunk of that building. The new fencing outside disappeared in one area, the old fencing reappeared, and the stray building materials that are there at the start of the game had reappeared inside my building. Thankfully my mansion seems fine so far, at least. Has anyone else experienced anything like this? Any way to fix it?
