Just want to say thank you again, MissDoh! My testing proves this out - the ghost indeed packages up nicely once another living sim on the lot sees it! Now I can move ahead with my project.  

Well, I've tried the low-hunger method, but the sim is not dying upon lot entry. He stands and waves around and complains. I lowered other things too, but to no avail.

So MissDoh, you're saying that, pre-packaging, I could quickly kill off Mr. Boddy so he's already dead, but then at least one of the other "cast members" would have to actually see his ghost in order for it to appear with the lot once the lot is packaged up for others, right? (Cast members being Col. Mustard, Prof. Plum, Miss Scarlet, etc.)

I could do that, I'd just have to be patient and wait for it to happen.  But with 6 other people in the house, one wouldn't think it would take that long. At least, one would hope.

Thanks, I'll give that a try, too.  

Oh my gosh, I don't know why that didn't occur to me! And that would be the absolutely simplest way to go, wouldn't it?  Here I am cooking up huge schemes and methods in my head.  LOL

Thank you so very much, KacoshiAjewl, I really appreciate that! And that you tested it.  Kudos!

I am working on the Clue Mansion and have sims ready to go - but I'd like to have a Mr. Boddy ghost walking around. However, my testing is showing me that once the lot is packaged with the gravestone, and installed fresh into the game, the ghost never shows up.

Is there a way to do this? To set it up so that a ghost shows up? I'm hoping to offer a lot without hacks included, if possible.

Another thought was to set up Mr. Boddy to be so sick that he'd die immediately upon entering the newly installed lot? Could I do that with InSim, do you think?

Any help is appreciated! Thanks!
