How do you get the gondola in my sims kingdom DS?

Once you've fixed Richard's compass, he'll let you cross the river. Upon arrival, to your left is a girl in a pink "winter outfit." She's Emily, and she mans the gondola that will take you up the mountain. She'll tell you to talk to her later at the gondola base. When you get there, in the very uppermost corner on the right hand side of the screen, she'll tell you the gondola base has disappeared along with the rest of the town. She'll give you blueprints to give to Torajiro (the carpenter on the other side of the river--walk as far left as you possibly can in the bottom corner) and tell you to speak to him and doctor F. Dr. F must be seen first, seeing as if you talk to Torajiro he will talk to you about "no lumber and steel" over and over (Dr.F will once again provide) and then give the Synth-O-Tron Mark II (the machine) to Torajiro. Talk to them once more, and get the needed essences (just for the base, you don't need the "molecule" essence) for the base. Then, talk to Emily again and the top of the mountain is once again accessible at your leisure.
