All the other stats work fine, it's just the % hit that doesn't.
The specific weapon skills work like this. Take a base randomised number between 0 and 5. Add to that base the modifier which is your weapon ability score divided by 10 (remove the remainder). That's what you hit for. So if you have a slash of 100, you'll hit for Random(5) + 10. If you have slash 46 you'll hit for Random(5) + 4. Then take into account weapons, a bastard sword will give you an extra +6, a great sword an extra +3. And finally to complicate matters, some moves work against particular foes better or worse. If you slash at a wolf you'll get an extra +3 to your damage. Or if you try and stab at a jaguar you will always do zero damage (your sword stab goes straight over the top of the jaguar.)
Current saved games will simply not work in the patched version, you try to load one it will crash the game completely out to Windows. That's simply the nature of the way the engine we use works it's internal code. It sucks but there's nothing we can do about it. That's one of the reasons we're taking a while on the patch, we don't want to patch more than once, and we're throwing in a couple of extra goodies as a way to apologize of sorts for making 1.0 save games redundant.
EDIT: Those numbers are based on the 1.1 patch, but I'm pretty sure they're the same in 1.0. Even if they're not, the numbers might be different but the basic principles are the same.
