Lately, I have been receiving random FALSE fire alarm messages, even though there is no actual fire. Why? My sim lives OffTheGrid in a tree house and has very minimal stuff on the lot. So there is no way I could overlook a fire. Is this a bug or is this supposed to be a fire prank/joke on the player? It's very irritating when you have to look around in every corner just to discover that there is NO FIRE. I then have to reload the game because all the menu tabs in the upper right, like Build-Buy-Mode, are greyed out and non-functional.
