Lot doesn't open, I don't have a mod and I play on PC

My game doesn't have a Mod, but when I enter the lots they disappear, on the map it appears when I enter to play the lot doesn't exist, please fix it, I can't stand having to reset the game and start again, I've had this problem since June, I haven't been able to play with any new expansion yet.
