Idle Sims/Not Performing Actions

Does anyone have issues where Sims just stand around and don't perform any of the commands you give them, or don't take care of their needs, I've found that the traditional fixes (resetting Sims, loading the lag fix mod, restarting game or repairing the game) don't work. I've been playing a household for a few weeks now and I suddenly encountered this issue since the July update.
