But your actual health, stamina and magicka values are increased, right? If it’s the same bug I’ve seen over the past years, it is only the food buff display that is wrong while your values actually are increased. I haven’t made notes to have any guess at what triggers showing the zero values.
Had this bug today and it wasn't applying the benefit of the food. Went to another of my characters and the same. Logged out from characters, logged back to them...still the same. I even restarted the game and it didn't change a thing. Frustrating, because my characters were dying in the dragon fights several times with just a wing smack when they normally wouldn't have!
