Really looking forward for a dev's answer.
Valckirion: well, I know that sucks man, but you can activate cheat menu (Camp > Take an action) and then go in Camp > Cheat Menu, and then click on "Find an item...", choose from range 96, and there are food items there. You can repeat to fill in your inventory, then disable cheat menu again. I know that sucks but it can help.
Edit : About the face, I found a solution. In your character screen, click on your portrait: you can edit it again!
