Please accept a solution if your issue is solved. XP is also appreciated

how do i resetsim? i only have one sim in dragon valley.even if she is doing something she freezes for a few then

goes again.My bf is having the same thing as well he has only one sim.

There's tons of other Sims (the inactives) that also get stuck. They also get reset with the Sim (that just puts them in safe location.

To use

1. Open the cheat console with ctl-shift-c
2. Type resetsim * (including the star)

aww ok what will that do for me.?

You're computer is fine. There are newer Nvidia drivers. The february one did have their issues so update those

• Are you using custom content or mods in your game ?
• Is it just one savegame or all of them ?
• What town are you playing ?

ok that didn't work she still freezes up . i am playing in custom mode no mods. I am playing in Dragdon valley .It started to do that

after i down loaded the game.

Does it do the same in another town/save game ?
