When a carnivore or custom origin that restricts origins:food attempts to fill a glass bottle with water or dragon breath, nothing will happen. Oddly, vegetarians can use bottles like normal. Adding glass_bottle to ignore_diet.json does seem to fix this, so it might be an issue with bottles being defined as food somehow.

I'm currently working on a fix for this.
