None of my food boosts are working after the upgrade, and I've had several lock ups working on the Twins
So here's what I know so far, I regain HP when I use food boosts, but the other boosts don't work. If I lose a fight with a food boost the game stops right before the screen pops up to say I didn't gain any treasures or experience with the NPC. It happened several times with the twins and once with Ghart on a side quest gathering wood in Feasterra.
