Well, I have some sims on a lot created by me (it's clean), well there is a sim that has her fortune aspiration, and since she is in a challenge, her aspiration goes down a lot and she starts asking for simoleons at the door, the problem is that the SIM goes through the fences that I put and there is only one door that is blocked by my main sim, she goes out to ask for the simoleons and then even though I take her to the right place, I saw her go through walls, chairs etc… What can I do? .. it must be some kind of bug, but I don't know what it is or how to fix it. Thanks

Do you know how to use SimPE?

If so go in and see if the flags have been set for that.
