As on screens, before and after eating cp150 blue food, my character's stats were increased just of 1152 health and 1023 stamina.
/ReloadUI nor reloading character didn't change anything.
I was cancelling the food from the effects in C menu, then eating again, multiple times, no change.
I think it happened when I tried to eat food in combat (some dolmen).
Any ideas?
