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.

I don't know how to use Simpe, tell me what I should search for at least... I only used SimPE with a tutorial to change a last name once.

I been away for over 6 years and have forgotten a lot of stuff.
Just don't edit anything but look here and see if it will help. https://modthesims.info/showthread.php?t=630456

#6 shows where to look, its the bottom pic of the 2. https://modthesims.info/showthread.php?t=501260

Why do you take me to tutorials about dead sims and that I have to resurrect them? This sim is alive. She was a werewolf but she drank the cure, tell me exactly where I have to look, because everything seems like a mess to me. Sorry, I don't know anything about SimPE and English is much worse.

Probably because it sounds like the sim has a ghost flag without actually being a ghost, since she can go through walls etc.

Clearing ghost flag is in post #2 in the second link.

Or is it possible you mean something else by "Go through walls, fences, etc." than how a ghost would behave? Other ways a sim would appear to go thorugh things is either by clipping (parts of them go through because of animation bugs, but they don't actually go through), or because of crowding (something is pushing on them until they appear to glide through an object, and they can appear on the other side). Both of these are small bugs that can happen in any game.

ahh so I could see what you wanted to tell me, sorry for my clumsiness, simmer22, thank you for your patience and telling me where it was exactly, I saw that I followed the steps and that sim had "ghost flags", does that just happen?... it is very useful to me, since sometimes I think it happened to another sim, but it died and I couldn't start a topic here on the forum, (I didn't have time), you don't know how grateful I am, thank you very much, I will check it tonight, but I think that was it!!!

Sounds like just one of those glitches. Should be fine if you uncheck the ghost flag.
