Whenever I tried to join the Nether Terrain job (under the Survivor Jobs), it says that the job does not exist
This is just an issue with a typo in the interface. I've added it to my to-do list to fix. You can use the command '/jobs join netherterrainstudy' to join the job manually for now.
I have now fixed the interface and the click-to-join function should work now - please confirm @Jdawger
