Sims can neither sleep nor woohoo on holiday
When trying to woohoo or sleep in China my sims just stand dumbly around the object (whether it is a shower or a bed, it doesn't matter) until I reset one of them, because the action can't be cancelled. When trying to woohoo in bed, I can do this only by getting them to cuddle, they woohoo but they get permanently stuck in the animation.
First thing I tried is resetting all of the furniture.
I then tried selling and buying new furniture.
I then followed the FAQ (deleted .package files and mods, cleared cache), but all to no avail.
This has never been a problem for me with this or any other of my sim families. The only significant things that have happened to the family since their last holiday are; a new member (via a marriage), one sim converted to a vampire, they hired a butler. This is also the first time the entire family have come on holiday rather than just one or two members.
I have the following expansion packs: World Adventures, High-End Loft Stuff, Ambitions, Late Night, Outdoor Living Stuff, Generations, Pets, Supernatural
