Gobsmacked and I'm Unsure What to Do

Something occurred in my game yesterday that was disturbing, to say the least.  I thought seriously about rolling back to see if things would turn out better, the way it should have turned out, but then I got to thinking. I haven't really made use of L & D, and that I should just roll with it. Then, I got miffed again. I haven't used all of the special events in the game, as of yet, but the ones I have used we're allowed to invite 15 guests. Not this one. You only get 8. Since I play large families, it was greatly disturbing to have to leave some out of the event. In fact, it's just plain wrong.

Now, I'm sitting here wondering if it was a glitch and that I really should rollback and play it over again. I hate to be so vague, but since I write up about what happens in my game, should I go with what happened I hate to give spoilers. I will mention there was a fire. Watching the person burn to death when my active Sims were busy trying to extinguish them, was hard. I do know such things can and do, sadly, happen in RL. My own husband lost two of his uncles to house fires when they were little. He never knew them. But it scars a family all the same. Not only were the attempts fruitless, Grimmie turned a deaf ear to the pleas.

So, if it were you, what would you do? Rollback and replay, or just move forward? I really could use a bit of advice on this. Please, and thank you, in advance.
