Sim cannot be interacted with...

[Avalikia]

One of my Sims become borked somehow a few simdays ago, but I only just now realized the exact nature of the problem.  (Long story short: I was blaming the problem on her ex-NPC husband, but just figured out that her, not him, who is causing the problem.)  When other Sims try to initiate actions with her nothing appears in her queue and it quickly disappears from theirs; if she initiates the interaction everything proceeds normally.  This started happening around the same time she got married during a date at her home - I suspect that may be related but I could be wrong.

Let's see, other relevant info...  I've tried resetting her, there are no unusual options available on the batbox and I've tried all of the usual options that I thought might help.  There haven't been any error messages lately.  She's a born-in-game Sim who hasn't had anything odd happen with her before.  I haven't had any other odd happenings in this particular neighborhood, so I'm thinking that whatever is happening is strictly limited to this particular Sim.  I have all the expansions (patched), none of the stuff packs, a lot of awesomeware, and minimal tight pants.

Any ideas on why this happened and what I can do about it?

I have only ever had this problem when I moved sims interhood, so I have always assumed that this problem is the sign of the apocalypse, at least for the hood in question.

Does this only happen on THAT lot, or does this occur even if the sim is invited over on another lot? If it's a condition that occurs only on the sim's home lot, and not other lots, the sim's object instance is probably broken, and you can just delete it, save/exit/reload, and it will respawn fresh by the mailbox.

@floopyboo - I don't do stupid things like that, and if I did I wouldn't ask for help when things exploded.

@Pescado - Deleting her and reloading the lot solved the problem.  Other Sims can now harass her normally.
