Brother Attacked Our Village

[Joe Friday]

Is there a known bug or rare game mechanic where a family member or party member will attack a friendly village? I just got a notification stating my brother was attacking one of our friendly villages. Unfortunately I could not take a screenshot before the message vanished.

It was most likely him defending the village from an enemy party that was raiding it. The notification is misleading.

It's a feature. Can confirm bros are really like that. 100% immersion
