Re: Can't move camera with mouse or mousepad
@Rinchan89 Please try switching back and forth between the Sims 3 and Sims 4 cameras; you can choose between them by clicking on the camera icon in the upper right corner of the screen. Quit, restart your computer, and reload the game in between.
If that doesn't help, try moving options.ini, in Documents\Electronic Arts\The Sims 4, to the desktop. This will reset all your in-game options, but if you don't want to redo them all and this step doesn't help, you can delete the new options.ini and put the old one back.
