Dwarven heroes only move a few squares (exept Engineer) per turn and do not fly.

For example, enemy ghoul has 60% hit chance, but he almost never misses. While my troops hit chance works fine. Medium difficulty.

I've never really played a game like this but often found games from this era very hard. So I was thinking of doing my first playthrough on easy, but is easy too easy or still a challenge?

I picked the Weapon Master ability for my Archmage on level up, but it doesn't appear in the list of hero abilities. Is WM missing, or is it just invisible?

So unfortunately I am not the most computer savvy, so please explain this like I am 5 lol. Lately when I have launched the game, a pop up comes out saying "C:\Program Files (x86)\Steam\steamapps\common\Disciples Sacred Lands Gold>.\Exe\Disciple.exe" and then the game turns completely red/black and looks like a "negative" image. This of course makes it impossible to play. Does anyone else experience this and have a solution? Thank you!...
