Um, does anyone know how to stop Sims from lagging? I use CC and have a Mac, and play on low/medium on laptop mode. It's been doing this for a while, and I even did a CC purge a while back, but now my sims won't stop just standing as time passes. I'll be playing for under 30 minutes before none of my sims or NPCs stop what they're doing. I'm not sure what to do. It's gottten worse in the past few weeks.
