Баги "Might and Magic: Heroes VI"

I downloaded a new torrent with patch 1.7. I installed it. I encountered the following problem: when entering a Castle, instead of the background with the buildings, I see black and gray squares and rectangles. This didn't happen in the earlier version of the game. I deleted it because the translation wasn't very good, as I downloaded it when the game was just released.
Thank you in advance.

I have a legitimate version, and this bug also occurs.
In general, the new patches have created new glitches; here are a few (although some may have existed before).
1. In the Campaign for Anastasia, when I besiege a city, large creatures (lamassu, spiders) can only be placed automatically: if you try to drag such a creature, it goes into reserve, and it is impossible to take it out from there. At the same time, the rest (small) creatures seem to "disappear" from the battlefield. Archers can shoot, and even without a penalty for obstacles, and melee units are generally in an "astral" state: their turn comes, but it is impossible to move them (although they seem to be in their places). The enemy does not see these astral units and, accordingly, does not attack them.
2. The "pathfinding" skill reduces the hero's movement range. This, I must admit, annoys me the most.
3. The "despair" skill increases the morale of the enemy creature.
4. During the Week of the Living, the initiative of living creatures increases by 10 instead of the declared 5.
5. It seems that some buildings that increase the hero's parameters for a week actually only increase them until the first battle. For example, when visiting the "Seal of Arkat," the hero's physical and magical defense increases by 5, and this is reflected in the hero's characteristics, but after the first battle, the hero's parameters return to their previous values.
