I had my very first meteor hit yesterday too, in Starlight Shores. All of the people in the area did the cowering/crouching/head-shielding pose, but then got stuck like that. My sim got burnt, but none of the other Sims in the area got burnt and some of them were even closer to the impact area than my sim was. Also, after the meteor my sim was controllable as normal, but all the other sims stayed in that crouched pose for days. At least 3 sim days went by and they were all still there, will "I'm hungry" and I'm tired" though bubbles. I don't know yet if they will still be there when I next play, but I hope not, as one of them is needed to complete an opportunity but my Sim cannot interact with her.
