Interview with @Hellboy in czech/slovak.
Several new things (for me) were said.
-When you kill someone and you won't loot him, passerby NPC will be like "oh look, armor!" and steal it themselves.
-When you kill a cow (or any other animal) the loot won't be 2 pieces of meat and milk, but 500kg of meat (depends on the weight of the animal). But you obviously can carry only small portion of it (Vavra gave example 30kg).
-You can try to take all the meat little by little and sell it or store it, but it will get bad fast and if you try to sell this much meat to merchants in a village, they won't want it, because they will have too much of it.
-In alchemy it will be possible to create bogus potions that don't work, like potion of love etc. You can sell them to people who believe in their power.
