Re: sims 3 keeps pausing like clicking pause button not freezing

Try resetting all your Sims in your town with resetsim *

To do so

• Open the cheat console with ctl-shift-c
• Type resetsim * (including the *)

This should put all your sims and animals to a safe location.

You might have a stuck Sim somewhere
