[AA] Sims stand around not doing assigned tasks on Custom Venues/Getaways

I'm noticing during getaways that sims become very delayed when moving through their role activities for each time slot.   Most of them on the lot become stuck (or a long a pause) and often times may not move again until the time slot changes to the next main activity. Or they may not move again until your 2 1/2 hours into the current time slot.  So when the time slot changes again to a new main activity, they'll stop mid action instead of finishing their current action (i.e. just grabbed a plate food to eat but placed on floor to go use the spin bike because the main activity changed).  Sims with more specific roles like chef, housekeeping/staff, entertainer and DJ which tend to do the same activities per time slot, would start about an hour in.  The DJ never showed up on time and did not start until it was almost the end of the 3 hour time slot.  I did try to adjust the amount of time slots, activities per time slot and number of guests to see if that made a difference, it did not.  The custom venue lot I was using was either 50x50 or 50x40 and I was doing 3-4 day getaways.  I did notice on a smaller lot I didn't have a problem but only tested it for one day on that one.  I also play on PS5.
