Mounting "base" directory as Bind Mount Doesn't Work

[Gunslap]

For reasons that escape me completely, if you switch the code to use the "/ja/base" directory as a bind mount and mount it to a local directory (with the assets{0-3}.pk3 in it) as I have in the dev-feature-BaseAsVolume branch... it doesn't work?

The game server will try to launch but for some reason is unable to see the .pk3 files:

weirdly, the file system sees the files just fine if you check the mount directory. Everything works fine in the original code from tofi92 where the files are mounted from another directory and then copied into base... it just doesn't make sense to me. Why can the container see the files, but the application running within the container cannot? Permissions on the files seem correct as well. I'm at a loss with this one.
