Hello, yesterday I was playing a challenge with special sims and the zombie sim died (I didn't realize the exact moment since I let the sims take care of themselves), I was looking for the grave and it's not in the lot, it has disappeared! I bought the phone to call the grim reaper and it says that there is no sim in the lot that I can recover, can't I do anything to rescue that grave?

You should be able to use the batbox to respawn the grave, just pause the game, summon the ghost to lot, make them selectable, and then the option should appear for them on the batbox.

Thank you very much for answering, because yesterday I loaded the game and the zombie sim was in the lot! It was burned by lightning, but it was already in the list of my sims on the left, how is that possible? A game glitch? I have that batman box, but I don't know how to use it, only the invisible SIMs, is there somewhere where I can read the tutorial for what each option is for and be able to translate it?

Probably just a glitch, sims can disappear from the sidebar sometimes if some glitch happens.

Oh.. it's the first time this has happened to me, I got a scare, I've already found the site where I can read everything about the batbox, wow.. I've clicked on all those options, I hope I haven't ruined my game ;$
