That sounds like me and my little girl Sophia in China. I'm having a devil of a time finding the right dumb keystone to go with the right adventure. So far I've found 2 keystones, crescent and heart, and adventures for others. Everywhere has an adventure and I can't get into any of them without hitting a dead end.
I have yet to get to Egypt because I don't want to tangle with mummies right now.
Sophia has her blue belt in martial arts and I'll be sending her bum to kick some mummy butt soon.
The one thing that really irked me was when I sent 2 sims to China they could stay for 6 days, which was nice, but the stupid general store where you buy the supplies, food and showers in a can, was closed the whole 6 days. Funny but the special merchant seemed to be a little ticked also.
Unfortunately I immediately thought, uh oh, glitch...but in France the merchant was there. Maybe the old boy in China up and died by the second trip.
