I was riding my ApexZDodo around in the swamp when I was dismounted by a kapro. Instead of switching to my character in the kapro's mouth, I "became" the dodo, was taking damage as the dodo,until it died, and only then did I "go back" to my character in the kapro's mouth. I don't know if this was just a one of vanilla bug, or related to how your mod handles bsing mounted, but I thought I'd mention it. I've been unable (and unwilling) to reproduce the bug.
