I was in Proudspire Manor messing about trying to put a grand soul gem on a shelf (it's bloody difficult on Xbox One) when I dropped it. Jenassa and the priestess of Azura whose name I forget started arguing about who was going to claim it. Before I could pick it up they were punching each other and then it got serious with swords and magic. Jenassa got the worst of it and died.
Is this normal? I've played 127hrs so far and not seen anything like this. Is it because they're both dark elves? Or do some followers just not get along?
I just reloaded a previous save and ordered Jenassa to stay upstairs (we're married with two kids and I quite like her attitude, so leaving her dead on a cellar floor seemed a bit rough) but do I have to be careful about this happening again? And,if the worst comes to the worst in the future, can I remarry?
