Lots of comments lately in chat, so it seems pretty generally an issue.
Swings going through various blocks. Mount and blade always had issues on very uneven terrain of swings going thru people. But now its much worse. Swings going through blocks and hitting people, and swings going through people without hitting them. In particular overhead swings seem affected.
Dunno what has or hasnt been done to the game. Some people say the game mechanics have been fiddled with. Whatever it is, please note that its messing the game up. Kinda a pain to swing through a guy 2-3 times on over heads and not hit him. And block up and get hit anyway.
Stabs too seem... odd. Miss a lot even if they go thru people.
