I've had confirmation from the devs about the correct folder strutcture for mod installation on Mac and Windows, but not on Linux, unfortunately. Since my first suggestion would be to make sure the mod folder is in the correct directory, I'm gonna have to trust you there.
There's no way for me to test my mod on an OS other than Windows either, so perhaps your best bet for now would be to download one of the reuploads of the patch some users have made on Steam Workshop and see if that version works properly for you - as ironic as that may sound.
