You have a really weird definition of “game breaking.” Slightly incorrect UI information for brief periods might be annoying or even frustrating, but it’s not “breaking the game.” Your game isn’t crashing, your save files aren’t being corrupted, your character is randomly dying nor losing rare items.
Anyway, under the new hunger system, it takes time for your character to register what they’ve eaten, and yes, there is a bit of a glitch in the UI.
Have patience:
- Eat a reasonable amount of food, and then wait a bit for your hunger indicator to settle properly.
- KorGenT is working on the issue in response to the non-angry feedback he’s getting, and has already made several improvements to it. This will get ironed out, but the point of the experimental version is that developers are experimenting with it and things don’t always work out perfectly.
