Hello guys. I play the Sims 3. There is a mission called travel to the future and speak with time traveller. After going back to the present and doing the given mission, I went to the future again, I spoke with time traveller but actually I could not speak with time traveller. Whenever I try to assist with a new research (?) he does not accept to give me any and he says that I did not do the given mission. Would you help me please?

If you would rather cancel it and move on, you can right-click on the box that shows its icon in the Opportunities tab. Even if the tab is empty, you can try right-clicking a few times; occasionally something gets stuck, and this can help. Then quit, delete the five cache files in your game folder in Documents, and reload. These cache files should be deleted regularly anyway, and especially when you're having game issues. For reference, they are:
