As you may see from the title, I have a jump bug. I've just installed the game on this computer with expansions all the way up to Seasons and the Glamour Life Stuff pack.
Since I normally make my own neighbourhoods, I decided to take a look around Pleasantview and I started playing The Burbs after furnishing one of the Maxis houses. Long story short, whenever I direct them to sleep they jump. The only way around this is to make John and Jennifer Woohoo as they then sleep after that with no problem, but poor Lucy does not have such an option

They're both Maxis beds, one's a double and one's a single. I've taken a look at the error log but it doesn't mention any mods. I've attached said error log to the post, can any of you sim wizards help me?
