Also I don't think this is right since I am fairly certain that when I bought Mount and Blade in like...2006 it had auto block and did not have manual at that point in time. It was the original blocking methodology, so presumably their game engine, if built in house, would have been built out with that in mind.It is in a larger function and was indeed inproperly implemented, but I don't think they build their engine with that idea in mind so it's clear that it would be the same this time around.
Unless you mean Bannerlord's engine (if different) in which case you're probably right.
