Describe the bug
When creating a new world in singleplayer after previously playing another world, the new world inherits the skill map of the previous world

Expected behavior
All new worlds should have fresh/blank skill maps

To Reproduce
Steps to reproduce the behavior:

1. log into a world where you have experience (or give yourself experience)
2. Log out of that world back to the main menu.
3. Create a brand new world and join
4. Your skills from world in step 1 will be present in this new world
5. log out of the game entirely
6. relaunch the game.
7. enter the second world
8. xp persisted between reloads

Versions:

• Minecraft: 1.19
• Loader: Forge-41.0.1
• PMMO: Dev

Additional context
This might be due to caching caused by Core. Since the JVM session is not terminated between worlds, data may be persisting between worlds. The registry keys for the save location will be identical since the overworld is the overworld in all saves.
