EDIT: Oops, I just realised you wanted a permanent fix. Sadly there isn't an option for this. Yet. I hope there is in future.

To disable Hugin...

1. Make sure you've got "-console" in the launch options for the game in Steam
2. Bring up console (F5)
3. Type "devcommands", hit Enter
4. Type "tutorialtoggle", hit Enter.
5. Esc to exit console

** Don't type the "", obvs.

Hugin may show up again, but talk to him once and it will turn it off for the rest of the tutorial.


Cheerio!
