sure have fun!
Will take a look at it, just take enough supplies for now
Do some research about it, you need a lectern in your house and the magic level to make a tab ^^
The easier the tab the lower your construction and magic level has to be.
Try restarting the client and login after hooking the mirror client, it shouldn't take a knife if you already have one.
Also check the console log for more info if you can (Settings->Show logger)
