I Need Some Help.

Okay, so not too long ago I bought the World Adventures expansion. You know how you get new hair, new clothes, and new Lifetime Rewards?

I don't remember if this one particular Lifetime Reward was there before I installed the expansion, but I purchased that 30,000 Bodybuilder Lifetime Reward for two of my Athletic Sims. Each time I've purchased it, I was told to look in the shared inventory. I've looked in their individual inventories, the dressers, the bookcases, the fridge, and I haven't found it. So I have no idea what the shared inventory really is, and I'm getting frustrated. They need to get more athletic for their jobs, and I spent 30,000 freaking Lifetime Happiness points for this Reward. I'd like to know how to use it.

Also (if you have the World Adventures expansion), are gold coins the only way that you can buy the martial arts stuff in China? And where can you buy camping supplies while you're in China?

Thank you! :D
