Long story short, was doing Whoreson Junior quest, was at casino, won the games, free'd the little prick and fought my way out. But for some reason every food i eat/drink ( not potions ) last 20 minutes, not 10 or 5 seconds. Is it normal? one water lasting me 20 minutes of vitality regeneration. I take another, resets counter back to 20 minutes.

Maybe you have a new skill from DLC? If it is true, so its normal.

Do you have any mods installed, and/or have you been using console commands?

Yeah i have been digging into it, it is a skill, though no freaking idea how i got it.

I dont have that new skill, i checked all the general skills, and skills i have unlocked/equipped. I am getting a boost for a skill i dont have and dont want. Why am i being so trolled :(
Bloody hell, another edit, its the "Huntsman" Skill, doubles the effect of the currently equipped trophy.. Let when i have that skill i get the 20 minute vitality boost. Anyways, got it cleared up. Not using that skill.

Yes mods no console command but i already posted about the problem, its cleared up but not sure if thats how its meant to go down. The effect the skill says, is completely different to what i get.
