Hello! I tried searching Grave & Tombstone and found nothing on the subject. Is there an option to change the Tombstone style? I have a dead sim that I feel deserves a much bigger headstone than the generic flat stone. Any options available to switch the style to the bigger headstone?

Hi there. According to the Sims Wiki, the gravestone a sim is granted should be dependent on the total number of LTR points they have earned throughout their lifetime. It takes 75,000 to earn a medium sized one and 150,000 to earn a large one. You should also be able to buy the larger ones with the BuyDebug cheat on. What I don't know is if there is a way to transfer the remains of an already deceased sim to a purchased but empty gravestone, perhaps someone else here has tried that.
