The title pretty much sums up the problem. I was watching her the whole time and she never got hysterical. Which is required to my understanding for a sim to die from laughter. I have mirrors in the both bathrooms and one is on the wall in the hallway directly behind the fridge. Ever since the first time this happened to one of my sims I watch it very carefully and send them to a mirror to calm down. I was allowing her to finish the meal she was cooking on the stove and was going to have her go to the mirror in the hallway when all of a sudden....you see what happened. And I didn't even think to exit and load my last save. So now I am having to fix this mess that should not have happened at "very playful" in the first place.
