Snapshots allow you to load worlds from the combat test snapshots

When hovering over a world created from the combat tests and then loading up the game with a version later than that combat test, the game would still allow you to run that world even though there are unsupported features like the Chopping enchantment, etc.
I have not tried to load the world in fear of corrupting it, so if I said wrong information I greatly apologize in advance.
