AI Captains doing night attacks?

I'd noticed this a handful of times in my last campaign, but kept forgetting to do a screenshot before I accepted the battle. This time, I remembered!

Are AI captains supposed to be able to initiate night attacks? That seems a little weird, to me. I guess it gives the AI an advantage of sorts, though it seems to do it completely at random and often to its own detriment. One of the FM's in the above screenshot has the trait, though as reinforcements I was under the impression that they can't use it. At least that is the case for players.

I've never encountered this, but I guess that it is caused by the reinforcing family member who has the 'night fighter' trait.

I figured it was something like that myself. Is there any way to fix this? It really hurts the AI more than me, usually, so I would benefit only from the increased challenge. I don't "think" I've ever seen a captain night attack me without a family member with the trait as reinforcements, but I've had it happen a bunch of times and accept the battle before remembering to check. Thanks for the reply!

I don't know it for sure, but since this is an internal BI mechanism it's almost certainly hardcoded which means that we won't be able to do anything about it
