I have some issues with the mod too. Not big but annoying. The Battle orders buff of the Barbarian is bugging out when I play in a party. It makes it so that my party members "see" that their health is rapidly decreasing to a point where all of their health is gone in a second even though I see on my end that they don't take any damage.
Also another strange bug in multiplayer only. After a point in the game, all of my stats start to increase constantly. Attack, defense, damage go up every second. I've seen them go up to 30K! even though they feel normal and I don't one shot creatures.
Also as Skanatov said, many textures of sets and uniques are missing or are replaced by red crosses where there was supposed to be a texture.
Otherwise thanks to your mod I am playing Sacred 2 again. Good job!
