'init-mod-universal-tailscale-postinstall' fails due to untar "cannot change mode" error

[coffeemonk]

I am consistently having issues spinning up a linuxserver/plex (public or latest) container with universal docker mod due to the following error:

tar: tailscale_1.80.0_amd64/systemd: Cannot change mode to rwxr-xr-x: Bad address tar: tailscale_1.80.0_amd64: Cannot change mode to rwxr-xr-x: Bad address tar: Exiting with failure status due to previous errors s6-rc: warning: unable to start service init-mod-universal-tailscale-postinstall: command exited 2

I have another container (on the same host) which launches without incident, however this new container for some reason cannot successfully untar the downloaded tailscale archive.

I have opened a console on the container and confirmed that all the files appear to have been extracted, but the error causes the init script to exit.

Have tried to fix it by manually editing the file to simply ignore the tar error, but ran into subsequent (presumably unrelated errors) that led me to recreate the container, thus losing my edits.
