worlds folder missing / world won't save

Hi,

I'm using your Docker on OMV4 and its running pretty fine. Thanks for your work!
My problem is, that every time my server reboots/the docker image stops/restarts the world and everything my kid has built is gone and a new world is created. I have no worlds folder in my /data folder. I have tried setting up, everything fresh, but it didn't work.

Do you have any idea why that is?

Thanks in advance!

Start by reviewing how the Docker container maps its /data directory and where the worlds folder is expected to persist on OMV4. Reproduce a container stop and restart, then verify whether the world and the worlds folder remain available afterward.
