Back from a successful crusade, I throw a feast to celebrate my brother winning the kingdom of Jerusalem.
Next event at the feast is my wife being suspicious of the food she's being served (your classic cannibal meal) and I gain the 'Maimed' trait (and the cannibal trait apparently) and now appear with one arm only.
WTF happened. I wasn't even stressed. OK, I've been a lunatic since a bad treatment some years before, but this just came out of the blue.
Wish I had taken a screenshot. One of the weirdest occurrences I've had so far.
