Dice roll is rigged? [KCD2]

I have a feeling, that when I, let's say we play for 1500 points total, get to the point I have 1400 points and opponents have around 800 points, they always manage to f-ing roll dice to win the game on the spot. Every single time.

And if I get lucky and get to the 1400 points and they get zero, they still mange to roll high result.

I think there's a script when the AI got full berserk and starts rolling absurdly high points like nothing.

I was looking also at the perks and there's nothing like a "Lucky roll" or smth from KCD1.

What is this?
