A lot of features went missing because I uploaded the wrong file, sorry about that. They have been restored.
You'll have to set the anvils again, you can either do this with commands or edit (with the server closed) the file anvils.yml and set there your values. In "anvils" you must put each anvil like 'world x y z' (i.e. 'hub 100 15 -13').
- Update: now all the messages are configurable, the "tab" key was added for commands names and worlds. Use "/ua help" in game to view all the available commands. If done from the console less commands will appear (because the console can't look at an anvil, for example...)
