Thanks, everyone. I think I found the problem. I had to restart from the moment I walked into the warehouse. You can't have Nancy stepping out of the warehouse between the time you walk her in and the time she gets the sapphire. If she gets out of the warehouse, and goes back in, she won't take the sapphire even after the four lasers are down. Guess the programmers have a bug :( ) Z* u- P+ }4 v8 Y7 }9 ]6 z% m; C% U以上为转帖内容。。
