During today’s Inside Maxis Live Stream, SimGurus acknowledged that they are working to find the root of the simulation lag issues in The Sims 4. They encourage players to head to Answer HQ or the official Sims 4 Forums and share their saves. Additionally, SimGuruNick has set up a special Google doc where you can share your game data with developers.
Simulation lag is an issue where your Sims stop performing actions. It's a symptom of a deeper issue and can have dozens of different causes. We're always working on it. Save files are always very useful though, could you share yours with me? Thanks much! https://t.co/hRkZy4x5vp
