I have the same problem! It has happened in different families, but all the Sims have died of old age so I cant say if its an issue with other deaths. I dont even have a chance to reset the sim because the game crashes everytime! Grim shows up, reaps the dead (the light-thingie comes out of the body) but the body doesnt disappear and then the game gets stuck on people crying around the body for about 10 seconds and then it crashes. I saved the game right before the death, so when I reopen the game the same Sim dies and the same thing happens and the game crashes again... I got around it by moving old sims to a different family before restarting the family I was playing in play-mode, but thats obviously not ideal... Its frustrating!! This problem has only showed up today... Can it have anything to do with resurrecting the sims tons of times before this? I used the death plant on Grim probably 20 times on these few Sims to keep them alive a bit longer but now when I have started to let them die and not plead or give Grim the flower the problem started. Before this I had no problems! I have also never used to death flower in any game before but it can be related to this right?
