How to extract the world data from the container.

[ajrohr]

Hello! I have a container running on my computer that I mounted to a directory on my desktop. When I access the directory, I can see all of the world data (worlds folder, server jar, etc.). I attempted to copy the world to a single player world, but upon copying the "/world" directory and loading it in Minecraft, the world data is changed. The player states (game mode, position in the world, inventory, etc.) are all reverted and the world is completely different. I can't find a way to do this. I tested this on a new container that I made some small changes to and loaded it onto a fresh installation of 1.20.4 (the same version the container was made in). Everything is Vanilla here. I'll include the compose file below. Does anyone know what's going on? Thanks!
