I have been noticing this for a while now. I don't know if someone has reported or made a post about this in the past but characters in the game wants to stand in the same spot, literally making them look weird. Here's some screenies from my crew topside:
They look like cells undergoing mitosis/meiosis or whatever 
but they are merging instead of dividing
They don't give me any problems gamewise just a weird two headed creature or like one of Capitan Salazar's undead sailors.
