Lol third message in this thread today Ambitions has alot of new stuff. I found out that you can change the present with the time machine. My sim went into the time machine and this message popped up after a while.

"Rebecca was walking along in the near past when she noticed a couple having an arguement. Rebecca told them to enjoy each other's company and think about the future and thier family. This seemed to work and the couple went away happily. Then Rebecca noticed how familiar they looked. Hopefully she didn't change the present!"

A boy pops up in my sim's home. I thought it would be her little brother (since the people she meet looked familiar and the only people she knows are her parents and her sister). Apparently this boy is her son and he has no father I think I found a glitch
