[PS] Simulation lag from initial load

While this issue has been around for a while after playing for several hours, since yesterday's patch it starts as soon as I load into a save. I keep having to pause the game for several minutes, every few minutes, for sims to "catch up" with whatever I queued them to do, or they will just stand there for literal sim hours doing nothing but idling, with the queued task just hanging there at the top, not started. This, combined with the general lag, makes playing the game increasingly frustrating.
