Configuration Files Overwritten

[ByteExceptionM]

Description:
Since my last deployment, configuration files such as paper-global.yml, paper-world-defaults.yml, and spigot.yml are being downloaded and used instead of the ones overridden by my image.

Related Release:
This might be related to the recent release: v1.38.16.

Steps to Reproduce:

1. Deploy itzg/minecraft-server:java21
2. Observe that the custom configuration files are not used.

Expected Behavior:
The custom configuration files provided in my image should be used instead of downloading the default ones.

Actual Behavior:
Default configuration files are downloaded and used, ignoring the custom files in the image.

Additional Context:
I have already checked my image and there are no errors in it. According to the logs, the configs are interpolated - but the downloaded files are used, as the active ones are definitely not my custom configs.

Please provide your container configuration since there must be an interaction with another feature I didn’t account for.

FYI moved this issue since it was directly caused by helper change.

Ah yes, it's probably not interacting well with the config mount mechanism. I'll investigate a better point in startup to do that.

For now the previous behavior will be restored after this image is pushed

Okay - great. Thanks for your quick help!
