This is what happens when I play The Sims 4, create EXO and leave them to do everything on their own in the game, while I play on my current household:

I have no words... Sehun was just going to make some food for himself while I visited with a sim from my household, and then everything started to burn and there was a fire, Baekhyun took it out and puh... I think now after a while and I haven't played on them... Some of the are dead and when I visited again there were even more fires...
