I have this "small" problem with my game. I can call up a friend and ask them out for an outing or a date on a community lot but as soon as my sim arrives to the community lot, the outing/dating partner is just standing there and there is nothing my sim can do to interact with the other sim. Also the game slows down remarkably. All the options are available for interaction but they are quickly removed from my sims' queue. This also happens when I'm throwing a party. All the invited guests show up but then just stand still and the time slows down to a crawl.
As I read some of my error logs in lot of places I saw the same lines over and over: "Visitor - Motive Check - Check Queue?" and "Function - Main - Loop" so I'm assuming the guests are in some sort of a loop?
I've removed any objects that might be causing this, but unfortunately it hasn't done the trick. I've also failed google for a few days now.
