I agree that this could be a very severe Sim pathing issue, at best. I've had every problem mentioned in this thread (and the 50+ page thread that was deleted), from the beginning signs of the game stalling slightly for short periods of time ; townie Sims and my own household of young adult - adult Sims becoming invisible or frozen while either exiting their cars outside of their rabbithole jobs, or being reset to home position when trying to enter rabbitholes for work; children and teenage Sims gathering in large groups in front of the school, unable to enter for whatever reason (recently with my current game, my two 3-star Celebrity teenagers will leave for school at 7am, arrive outside of the school on time, stand directly in front of the school doors as other neighborhood Sims gather, but will not actually make it inside the school and begin improving their grades until after 11-12 o'clock, giving them barely an hour to be in school, negatively impacting their performance and mood.).
Someone mentioned in the deleted thread something about when experiencing the disappearing or automatically reset Sims problem, they discovered that their Sims could be found on the basement level (even if there was no basement - they would be trapped underground with no possible route to escape except for the resetSim cheat). That made me wonder - though I have yet to check myself, because luckily I have not encountered invisible Sims since I began using Overwatch, Master Controller, and NRaaS Story Progression - if maybe there is a major issue with routing Sims on the way to rabbithole places, mainly for work, that they are for some reason leaving their cars or carpools and then being sent to a nonexistent basement level outside of the rabbithole building. It makes sense to me, because when I first started having these problems in Bridgeport (I'm currently playing in Sunset Valley), the plumbbob of the invisible Sims would appear not distinctly, and possibly slightly lower, closer to the ground, as if they were a level beneath the ground. The plumbbobs would still be visible for me, but they would not be as big as they should, and not in the correct full form.
I also had problems in Bridgeport with every single highrise bar or club, with a myriad of mixologists appearing in the lobby unable to access the lounge/bar area, which was also inaccessible to my active Sims, and when my Sim would attempt to enter the elevator with a small group of other townie Sims, he would be reset to home position and never reach the floor of the lounge.
It seems as though pathing is seriously corrupted when it comes to Sim routing, rabbitholes, and high rise buildings. Hopefully we can investigate this further ourselves as players and potentially narrow down the problem if/when EA takes notice of our issues.
