One of my Sims (the townie that I married) fulfilled her lifetime wish, so I killed her. Her grave is right in front of the toilet. My other Sim tried to use the toilet, stood on top of the grave, and complained about the grave being there. I tried selling the grave and deleting the grave, but they said "Can't be picked up" and "Can't delete," respectively. How do I at least move the grave? Thanks for answers.
Why would you put a grave in your bathroom? Anyways, just get rid of the bathroom and build around it (making the grave actually outdoors) then rebuild the bathroom elsewhere.
You don't put the grave in the bathroom, your sim just happens to die there and that's where it ends up.
There's no debug mode option for the 3DS version? I know the PC version has a debug mode that lets you move and delete stuff, even if it tells you that it can't normally.
