Yup, ever since they added in the citadel armor mechanic and whatnot, the guns and shells just don't work anymore. No point in playing when shells that have ridiculous levels of penetration seem to shatter on full broadside ships at point blank range, only getting deck hits/bounces at point blank range, and really bad hitboxes. Funny thing is that the game was less broken when it wasn't on Steam yet and all these continuous updates just keep breaking the ship mechanics.
