I can't seem to find a way to contact Hurrican about the shortage. I'm hoping they're active on this BGG page about their game!
You can try the following:
At http://www.hurricangames.com/en/games on the bottom, left klick the option "Do you want to contact the AS service ?"
Send an email to firstname.lastname@example.org
Contact them via Facebook https://www.facebook.com/pages/Hurrican/221897227872676
Hopefully this will help you out.
