Questions:
- Can I add/remove this mod to a saved game?
- Short Answer: Yes
- Long Answer: This mod uses a blueprint patch for each consumable type changed. This means the blueprint is modified at runtime, so savefiles aren't affected.
- Is this mod compatible with X mod?
- Short Answer: Most likely. I haven't found any conflicting mods yet.
- Long Answer: If a mod modifies the same consumable fields as this mod, load order will determine the winner.
