Hi! As you may or may not know, there is a NEWER version of this scenario, entitled "Medieval Blood (Version D Fixed) *New!*" It is enhanced with new features and bug fixes, and offers better gameplay. If you wish to download this version of the scenario (Version C), that is fine, but if you want to download the newest version of Medieval Blood,(Version D Fixed), you can find it a little ways up on the multiplayer page.
Thanks, and good playing to you!
