I had something that I thought was rather random happen in another game. Thought I'd post here to see if anyone else has experienced it.
Had a family (the one Anna is from, actually) and the woman married to Anna's brother was the oldest. My lifespan is set to 100 sim days... she lived to 112 and then died. I didn't find that too odd as I know sims can live quite a bit longer than their lifespans.
This is the odd part.
She was playing chess with her husband (Anna's brother). Grim turned up, so she stood up and did the whole dying thing. Her husband was 102 days old at this point AND had completed the jogging challenge so he would have a longer life. Literally, as soon as she completed her death animations, he died. Poor old Grim didn't even have time to leave the lot!
I found that... really rather odd...
