I figured out the issue for this problem, the default location for the ServerFiles (/serverdata/serverfiles) container path is directed from /mnt/cache, I'm assuming for performance. My main directory for appdata lives on 'cache_protected' so I was adding the plugin mod to /mnt/user/appdata without luck. Once this was changed in settings to the correct serverfiles location, and I copied over map files, everything worked and mod loaded in.
