You will want to create a new Player, there have been major structural changes
Desert
* (Add) Bodies of Water added into the generation of Desert biome.
Pathfinding
* (Update) Logic improved. Sentients can move around *most* situations, but still not all.
Campfires
* (Change) Campfires will only exist in a single instance of a Game. That is .. if you save your game and load it again, any Campfires that you have placed on the ground will no longer be there. This may change back in the future.
Structure
* (Change) Base changes to almost all structures for better key-ing, sorting and finding. This will require a new Player to be created (and a new Game, but that comes with the Player).
Sheep
* (Fix) When below Max, the width of the Sheep’s Healthbar was being incorrectly calculated.
